PhACT - Philadelphia Association for Critical Thinking

PhACT - Philadelphia Association for Critical Thinking Website http://www.phact.org We are the Philadelphia Association for Critical Thinking (PhACT). Our difference? We are not afraid to admit we don't know.

We love tough questions, but we maintain that there is only one way to find trustworthy answers: to use reason and to experiment. We reject wishful thinking, anecdotes, revelation, unsupported authority, and "everybody knows." We ask only, "What are the facts and what can we deduce from them?"

Of course, we don't know all the answers; nobody does, whatever they may claim. There are many questions which cannot be answered now and some which may never be answered. Critical thinkers don't invent answers when there are none. We would rather suspend judgment than mislead ourselves and others. PhACT encourages people to think critically about their beliefs and about the validity of the information presented to them. PhACT does not presume to tell people what to think but it does give guidance in how to think. Like Josh Billings, we believe that what hurts you more is not what you don't know but what you know that isn't so. We do not arbitrarily reject anything unexamined. Instead, we encourage the responsible scientific investigation of paranormal and fringe-science claims. Our aim is to promote scientific inquiry, media responsibility, critical thinking, and science education. PhACT is a 501(c)(3) non-profit tax-exempt organization. All deductions and membership dues contributed to PhACT are tax deductible as per IRS regulations. Please consult a tax advisor for information regarding tax deductions.

A thought for a Wednesday evening from PhACT - Check out our video collection on YouTube!

We have talks ranging from archeology and other science content to many on skeptical topics.

I hope to have a Wednesday evening thought every Wednesday (unless I run out of ideas -- is that possible in this area???)

Why have so many Americans seen ghosts?

One in 5 Americans say they’ve seen a ghost. America, the UK, and Ireland are as the countries with the most haunted locations. However Japan, Mexico, and India have the most ghost sightings of all other countries.

Science has advanced enormously in the past 500 years, guided by experimental tests of theory and practice. In that same time, science teaching and education—guided primarily by tradition and dogma—has remained largely medieval. Carl Wieman will discuss research from university classrooms that r...

A 25-year-old hiker says she snapped an “inhuman” Bigfoot-like figure wading through a murky pond - but online critics insist the viral “Syracuse Figure” is more likely an overweight elderly man skinny-dipping

Spoiler alert -- he wasn't really psychic. Just clever!

You might be surprised by how many researchers who went on to make important contributions considered whether animals could have telepathy.

Nancy Guthrie has been missing for seven months. Police have few leads, and her family is still waiting for answers.

CFI’s Investigations Group contacted dozens of America’s best-known psychics and mediums to help find her.

Some didn’t respond. Others offered explanations for why they couldn’t get involved. None provided specific, verifiable information that could actually help investigators.

As CFIIG’s Jim Underdown put it: “Give us an address, not excuses.”

If paranormal abilities work, this is the time to demonstrate them. Read about the Nancy Guthrie Challenge:

OpenAI, Anthropic, Microsoft, Google-parent Alphabet, Amazon and many more said that a wave of AI-powered cyber attacks is coming and that the world is not prepared.

Those hacks pose a risk to the “companies and public services our communities depend on .. from hospitals to water treatment plants to the infrastructure that powers the internet”, the open letter signed by more than 100 companies warned.

[And we haven't achieved (supposedly) Super Intelligent AI, or Quantum AI, or a 'singularity' event YET!]

“Cyber capabilities are advancing worldwide, and that can be a net positive: no single company should control the future,” the letter warned. “It also means a global response is necessary, requiring new partnerships to raise security standards and find new solutions to emerging cyber threats.”

"In the coming months, ​AI-enabled ⁠cyberattacks will become far more ‌widespread as models around the world become increasingly capable," the letter said. It called on government and industry leaders "to bring ‌the full weight of their technology, resources, ‌and expertise to this effort."

"make cyber defense an immediate leadership priority."

⁠In June, the world's "Five Eyes" intelligence alliance — composed of the US, Britain, ‌Canada, Australia and New ​Zealand — issued a rare ‌joint statement warning that the ​AI revolution was poised to "fundamentally transform" cybersecurity.
