CRITICAL THINKING VERSUS FAKE NEWS

 CRITICAL THINKING VERSUS FAKE NEWS

When my former Political Science professor at UP, Dr. Clarita Carlos, urged us not only to ask who, what, when, and how — but also why and so what — she was calling for more than curiosity. She was championing critical thinking. And in today’s age of fake news, deepfakes, and AI-manipulated media, that kind of thinking isn’t just useful. It’s essential.

What Is Critical Thinking, Really?

Critical thinking is more than just asking questions. It’s a disciplined process: analyzing facts, weighing evidence and arguments, and forming judgments rooted in reason, not bias or emotion. It’s a skill set — logical reasoning, evaluating sources, solving problems — combined with a disposition — open-mindedness, skepticism, reflective inquiry. The goal? To arrive at sound conclusions and to make informed choices.

This is not abstract philosophy: it’s arguably the armor our students need in a world saturated with manipulated content.

The Threat of Fake News and Deepfakes

Lately, I’ve been seeing warnings in my Viber groups — AI-generated videos and voice clips that feel real, but are entirely synthetic. These deepfakes are not just harmless pranks: they can influence public opinion, mislead citizens, and even sway election outcomes.

And the data supports this fear. Trend Micro has cautioned Filipinos that as we head into the coming elections, “anyone can produce deepfakes just by grabbing a photo … to make someone appear to do or say something they never did.” The Commission on Elections (COMELEC) itself is considering a ban on deepfakes and AI in campaign materials, warning that malicious use undermines election integrity. 

Tsek.ph, a fact-checking coalition, documented nearly a dozen likely deepfakes during the campaign season — from endorsements using fake voices to composite avatars of public figures. In some cases, 45% of the conversation around election candidates on social media was driven by inauthentic or coordinated accounts.

Why Critical Thinking Matters More Than Ever

When deepfakes proliferate, asking who made this? or how was it made? is no longer sufficient. We must also ask:

• Why did someone create this video? Is it propaganda? A political smear?
  
  

• So what if people believe it — what are the social, political, or institutional consequences?
  
  

Critical thinking empowers us to interrogate not just the source of information, but its purpose and impact. It means recognizing emotional appeals, checking assumptions, demanding evidence, and reflecting on bias — both ours and the creator’s.

---

But — Can We Detect Deepfakes?

Yes, to some extent. Detection tools are advancing. Some use sophisticated AI to spot inconsistencies in pixels, voice patterns, or even subtle physiological clues. Intel, for example, developed a platform called FakeCatcher that analyzes blood flow changes in video pixels to detect fakes. Researchers are also building watermarking technologies and proactive detection frameworks. 

Still, detection is not a silver bullet. As technology evolves, so do the tools of deception. And that’s where education becomes our first line of defense.

Teaching Critical Thinking in Practice

So how do we embed this in our schools?

1. Media Literacy: Teach students to evaluate sources, differentiate fact from opinion, and verify before sharing. UNESCO, for instance, warns that many content creators do not fact-check before posting — pointing to the urgent need for training.
   
   

2. Reflective Inquiry: Ask students to regularly play “why” and “so what” when surveying any piece of content.
   
   

3. Civic Resilience: Encourage participatory spaces (like barangay discussions) where citizens practice these skills together — building a community immune system against disinformation.
   

Dr. Carlos’s words keep ringing in my mind. If we only teach students who said it, when they said it, and how they said it — we stop short. We give them the tools to identify an image or a clip, but not necessarily the capacity to resist manipulation. By encouraging why and so what — by nurturing critical thinking — we prepare our students not just to recognize fake news, but to challenge its power and to demand better from their democracy.

In the fight against AI-driven falsehoods, critical thinking isn’t just a skill. It’s our strongest weapon.

WHAT COULD BE BETTER THAN PLASTIC?

 WHAT COULD BE BETTER THAN PLASTIC?

For decades, we looked at plastic as the villain of modern life — polluter of oceans, killer of turtles, clogger of esteros. And rightly so. Traditional plastics last for hundreds of years, break down into microplastics, and only a tiny percentage ever gets recycled. So the logic was simple: replace plastic with something biodegradable — seaweed, bagasse, hemp, rice straws, bamboo woods, anything natural.

But what if what’s better than plastic… is also plastic?

Out of nowhere comes a new material called Lyfecycle, a proprietary “self-destructing” plastic. At first, rumors claimed it was made of seaweed. But as it turns out, it is plastic after all — but the good kind, if there is such a thing. Developed by UK-based Polymateria, Lyfecycle behaves like regular plastic during its useful life. It’s strong, durable, recyclable, and compatible with existing waste systems. But the magic lies in the additive built into it.

If it escapes collection —meaning if it ends up as waste, it begins to biodegrade in open air, transforming within two years into a harmless, earth-friendly wax. And most importantly: it leaves behind no microplastics.

It is plastic redesigned with a fail-safe mechanism. A “just in case it becomes litter” technology.

Remember the old saying: “If you can’t lick them, join them”? Maybe that’s where we are today. We aren’t winning the war against plastic — not by a long shot. Global data shows that less than 10% of plastic packaging is actually recycled. The rest leaks into nature, where it stays for centuries. So if we cannot eliminate plastic overnight, the next best thing may be to use a better, safer plastic — one that doesn’t haunt the planet forever.

Of course, Lyfecycle is not a perfect solution. During the two-year window before it breaks down, marine animals could still ingest it. It won’t solve all environmental problems. And it’s not meant to replace natural biodegradable materials like seaweed, bagasse, or bamboo. These alternatives remain superior in many situations.

But as another saying goes, “You can’t win them all.” Maybe we can at least win some battles by using materials that won’t leave microplastic ghosts for the next 400 years.

Interestingly, the first major Southeast Asian rollout of Lyfecycle came from a surprising sector: coffee shops. In 2024, ZUS Coffee introduced Lyfecycle straws — durable like regular plastic, but biodegradable after disposal. They launched them in over 600 branches across Malaysia, making it one of the biggest deployments of this new technology. Customers welcomed the move because, let’s face it, soggy paper straws have tested the patience of even the most environment-loving consumers.

So the big question: what will the Philippine government do?

Since we are not banning plastic, we cannot logically ban Lyfecycle materials either. In fact, shouldn’t we encourage alternatives that are demonstrably better? Why not provide incentives to companies that bring biodegradable, microplastic-free plastic technologies to the country? Why not pilot their use in high-leakage sectors — food packaging, e-commerce mailers, beverage companies, supermarkets?

This is where policy must evolve. Instead of the endless cycle of bans, penalties, and cleanup drives, we need transition materials and transition strategies. Lyfecycle is not the final destination — but it can be a bridge.

Imagine barangays using Lyfecycle bags for their wet markets. Imagine sari-sari stores shifting to biodegradable wrappers that won’t survive long enough to pollute creeks. Imagine LGUs awarding “Green Procurement Points” for brands that adopt next-generation materials.

We often say we want to move toward a circular economy. Well, here is one opportunity to actually walk the talk.

So what could be better than plastic? Sometimes, surprisingly, a smarter kind of plastic. One that knows how to disappear when we humans fail to dispose of it properly.

Because let’s be honest: we still have a long way to go before we fix our waste management mess. In the meantime, if some plastics can clean up after us — even just a little — then why not let them help?

WHO CARES FOR CANCER CARE?

 WHO CARES FOR CANCER CARE?

Cancer is not just a disease — it is a systemic failure. In the Philippines today, we see this reality drawn in stark numbers: over 180,000 new cancer cases reported yearly, and 466,000 Filipinos living with cancer within the last five years. Every day, we lose more than 300 Filipinos to cancer, according to recent cancer-summit data. 

These are not just statistics — these are lives undone, families saddened, and dreams stunted. What’s worse, these may be conservative figures: many cancer cases among the poor go unreported, uncounted.

Yet, for all this burden, we lack a national cancer institution at par with the Philippine Heart Center for heart disease or the Lung Center of the Philippines for respiratory illness. Instead, cancer care is fragmented. Yes, we have several cancer treatment centers — but none fully symbolizes the unity, capacity, and recognition of a national “cancer hospital.”

At the heart of the nation’s public cancer fight is the PGH Cancer Institute, part of the University of the Philippines-Manila — not under the Department of Health. That distinction matters. Because PGH is funded through the UP education budget, not via the health department, when key funding is cut, there’s no simple line to repair.

Dr. Jorge Ignacio, who led the PGH Cancer Institute for 15 years, has sounded the alarm. In a recent public statement, he described the collapse of the Philippine health-insurance system: “Bagsak na ang health insurance natin … kawawang Pilipinas.” That’s not hyperbole — it’s a tired oncologist’s cry of frustration. He warns that the ₱100 million monthly allowance that PGH once received has reportedly been discontinued under our current administration. Without that, operations suffer.

The consequences fall hardest on the poor: over half of PGH’s 70,000 cancer patients are indigent, and about 40,000 depend on affordable chemotherapy. On average, PGH treats 500 cancer patients daily, many of whom cannot access newer, expensive therapies and are stuck with older, more affordable chemo.

The COVID-19 pandemic made things worse. Dr. Ignacio noted that many patients have deteriorated because they missed treatment, and PGH is bracing for a surge in delayed-care cases.

Even worse, beyond Dr. Ignacio’s warning, we lack public transparency. Has the funding for PGH’s Cancer Institute been restored? Is it covered under “Zero Balance Billing” (ZBB)? Do PhilHealth Z-Benefit packages reliably support cancer care in other hospitals? These are questions the government must answer.

Some efforts are already underway, but are they enough? The National Integrated Cancer Control Act (NICCA), for example, was supposed to expand access and create a Cancer Assistance Fund — yet implementation lags. PhilHealth’s Z-Benefit Package now covers breast cancer up to ₱1.4 million per patient, a big leap from its former cap of ₱100,000. But this is only for certain cancers and accredited hospitals.

Indeed, PhilHealth just reaffirmed its commitment to cancer care when it pledged support for the Philippine Cancer Center, a 20-story comprehensive facility in Quezon City. This could be a game-changer — if implementation is handled with urgency, equity, and transparency.

Beyond policies, we need systems thinking, governance reform, and community empowerment. Here’s what must happen:

1. Appropriate a dedicated cancer-care budget in Congress. Cancer is not an optional health concern. It must be funded like any other national-level public health priority.
   
   

2. Ensure national coordination. We need a centralized cancer center, working in tandem with regional hubs, not a fragmented patchwork.
   
   

3. Expand PhilHealth coverage. Z-Benefit must grow to include more cancers, more hospitals, and more Filipinos. And we should push for true No Balance Billing for poor patients.
   
   

4. Support early detection and prevention. Mobilize community-based cancer screening, host HPV vaccination drives (especially for cervical cancer), and strengthen public health education.
   
   

5. Make cancer care sustainable. Support PPP models like the new UP-PGH Cancer Center — but ensure public oversight, so public services remain public.
   
   

So again I ask: Who cares for cancer care, really? Is it us — ordinary Filipinos, patient groups, doctors — or will we let it be an afterthought? Dr. Ignacio’s warning is not a lament but a call to arms. We must listen, act, and demand accountability. Because cancer does not wait.

RETHINKING OUR HEALTH INSURANCE SYSTEM

 RETHINKING OUR HEALTH INSURANCE SYSTEM

Many years ago, when I was still the Director General of the National Computer Center (NCC), I approved the very first Information Systems Strategic Plan (ISSP) of the Philippine Health Insurance Corporation—PHILHEALTH. But before I signed off, I imposed one non-negotiable condition: the ISSP had to be designed for an insurance company, not for a welfare agency.

My argument was simple. If PHILHEALTH is an insurance company—as its charter clearly says—then it must operate on the strength of its premiums, its actuarial science, and its financial discipline. Insurance lives or dies by mathematics. Once you distort the assumptions, the whole model collapses.

Later on, I learned that PHILHEALTH quietly modified that ISSP to reflect a different worldview—that it was practically a quasi-welfare agency. In principle, I have no objection to the government paying for the premiums of indigent Filipinos. In fact, that is the correct approach. But even if the State subsidizes poor members, the core identity of PHILHEALTH as an insurance company should never be erased.

This is where the trouble began. When you treat PHILHEALTH like a welfare agency, suddenly the rules of insurance accounting become optional. And when the government begins to take money out of the fund—as if it were a convenient piggy bank—the integrity of the entire actuarial foundation is shaken.

But let us ask the basic question that no one seems willing to say out loud: Does PHILHEALTH’s money belong to the government? Or does it belong to its members?

I will say it plainly. PHILHEALTH funds are contributions from workers, employers, OFWs, and voluntary members. They are not government savings. They are not national revenue. They are trust funds held on behalf of the Filipino people.

The government may subsidize indigent members, yes. But that generosity should never be used as an excuse to turn PHILHEALTH into a welfare office or to interfere in its internal operations without transparency and consultation. And certainly, the practice of siphoning PHILHEALTH reserves to fund unrelated national priorities must never happen again.

In fairness to PHILHEALTH, it deserves the chance to defend itself from allegations of insolvency. But credibility cannot be restored by press releases. We need structural reform, not cosmetic messaging.

What exactly needs rethinking?

First, we need to move away from purely transactional fee-for-service models and shift toward preventive, capitated, and community-based care. We must reward health outcomes, not paperwork.

Second, decentralize stewardship. Allow LGUs and barangay health boards to co-manage funds, monitor service delivery, and prevent leakages. Local accountability often works better than distant bureaucracy.

Third, treat health as a public commons, not a commodity. Education, indigenous wellness practices, nutrition, and environmental health should all be part of the equation—not just bills in a hospital corridor.

Fourth, harness transparent, tech-enabled monitoring. Platforms similar to DIME, BuildTrust, or Bisto Proyekto can trace every peso, every result, every claim. Visibility breeds trust.

Finally, dignity must be the core metric. Does our system respect the patient? Zero Balance Billing sounds good on paper, but the poor should not be humiliated or neglected in our hospitals. Health insurance should restore dignity, not strip it away.

The future of PHILHEALTH must be modular, scalable, and community-informed. And reform should not be left to technocrats alone. The patient, the barangay health worker, the frontliner—all must have a voice.

Let us rethink the system not only to heal bodies, but to heal the social fabric itself.

CAN WE CONVERT SALT WATER TO FRESH WATER BY USING ONLY SMALL DEVICES?

CAN WE CONVERT SALT WATER TO FRESH WATER BY USING ONLY SMALL DEVICES?

Believe it or not, the answer is yes. And not only yes—we’ve been doing it for decades, long before “climate resilience” became a buzzword. Today, small portable desalination devices can turn seawater into fresh drinking water using nothing more than solar power, manual pumps, or small-scale reverse osmosis systems. They are already used by humanitarian groups, remote communities, and fishermen who need reliable drinking water on the go.

These devices could be lifesavers during emergencies, but here’s the real point—many barangays in the Philippines may need them every single day.

Water scarcity is no longer a distant threat. Even coastal communities surrounded by water are running short—not because they lack seawater, but because their freshwater sources are getting saline. This quiet crisis is called salinization, and it is happening all over the country: in Bulacan, Pampanga, Bataan, Cavite, Cebu, Negros, and parts of Mindanao. Wells that used to provide drinking water now taste salty. Aquifers are being infiltrated by seawater. And as sea levels rise, this problem will only spread.

Without fresh water, communities cannot cook, clean, irrigate, or drink. No economy, no household, no farm can run without it. Water is not just a convenience—it is survival.

That brings us back to the question: can small devices really help?

Absolutely. Some compact desalination technologies now available include:

• QuenchSea – Hand-pump powered, can produce around 3 liters per hour, ideal for emergencies or daily use.
• Rainman Watermaker – Portable reverse osmosis system producing 50–140 liters per hour, used by remote islands and sailors.
• MIT’s solar desalination prototype – Uses sunlight alone, with no filters, no high-pressure pumps, pointing toward future ultra-low-cost solutions.

These devices rely on technologies such as reverse osmosis, solar distillation, electrodialysis, and atmospheric water harvesting. The key is that they don’t require large power plants or massive infrastructure.

And this brings me to one of the most remarkable innovators in this field—a woman the world almost forgot.

Her name was Mária Telkes, a Hungarian-American scientist known during her time as “The Sun Queen.” During World War II, stranded pilots and shipwrecked sailors in the Pacific survived because of a small solar still she invented. This device, which fit inside a life raft, turned seawater into drinkable water using only sunlight. No electricity, no moving parts, no fuel—just evaporation and condensation. Her solar still saved countless lives, and it remained standard equipment for the U.S. Navy and Air Force into the 1960s.

Telkes did not stop there. In 1948, she co-created the Dover Sun House, the world’s first home heated entirely by solar energy. She held over 20 patents and pioneered technologies still used in today’s solar and thermal systems.

Her legacy is simple but profound: the sun can save lives.

So why can’t we apply the same thinking today?

If salinization continues—and it will—the government must know where it is happening, how fast, and what communities are at risk. That should be a priority national mapping program, ideally led by DOST, in coordination with DENR, LGUs, and water districts. Once the hotspots are identified, small desalination devices could be deployed in barangays, evacuation centers, fisherfolk communities, eco-villages, disaster shelters, and off-grid islands.

Of course, portable devices are not the ultimate solution. But they are a practical, immediate, scalable intervention that can prevent suffering while long-term water management systems are built.

The question is not whether we can convert salt water to fresh water with small devices.

We already can.

The real question is: when will we begin using them where they are needed most?
