Jesus Toast: Pareidolia You Can Believe In!

Posted by mattusmaximus on December 3, 2011

As a fun way of sharing some skepticism of “miraculous vision” claims, I wanted to share with you a really funny YouTube a friend sent me.  It pokes fun at the phenomenon of pareidolia, wherein people claim to see all manner of wild things – Jesus, the Virgin Mary, aliens, Michael Jackson, etc – in everything from the clouds to their shower curtain.  Of course, we know from modern science that these are illusions of perception, because our brains are marvelous pattern recognition machines, causing us to sometimes see things that are not really there.

Okay, enough seriousness.  Time for some fun… check out the “Jesus Toast” video, and share it with a friend.  Enjoy! :)

The “Invisible Gorilla” and How Seeing is NOT Always Believing

Posted by mattusmaximus on July 19, 2010

We’ve all heard the oft-repeated phrase: “Seeing is believing” – as if our human senses (specifically that of sight) are somehow, magically infallible.  Of course, most people don’t want to admit just how fallible our senses can be – or, more to the point, most people aren’t willing to admit just how fallible their own senses can be (they’re more likely to admit that other people’s senses aren’t up to snuff).

As anyone who has experience with court cases & law enforcement can tell you, the least reliable kind of evidence is typically that of eyewitness testimony, because we tend to place an over-reliance upon our senses in place of other, more rational & consistent forms of evidence.  Not only that, but our tendency to over-emphasize the trustworthiness of our senses can lead us into fooling ourselves that we’re seeing ghosts, alien spacecraft, the Virgin Mary in a grill cheese sandwich, and similar deceptions.

The fallibility of the human sense of sight and the associated phenomenon of inattentional blindness is beautifully outlined in this recent Livescience.com article…

‘Invisible Gorilla’ Test Shows How Little We Notice

A dumbfounding study roughly a decade ago that many now find hard to believe revealed that if people are asked to focus on a video of other people passing basketballs, about half of watchers missed a person in a gorilla suit walking in and out of the scene thumping its chest.

Now research delving further into this effect shows that people who know that such a surprising event is likely to occur are no better at noticing other unforeseen events – and may even be worse at noticing them – than others who aren’t expecting the unexpected.

The Hand of God?

Posted by mattusmaximus on April 7, 2009

There is an image from the Chandra X-Ray Observatory which is all over the Internet these days. Here it is…

What do you see? Most people, when asked, say they see what looks like a large ghostly hand reaching towards the nebula to the upper right of the photo. In actuality, according to NASA, the picture is an x-ray photograph of a young pulsar, or rotating neutron star

A small, dense object only 12 miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years. At the center of this image, made by NASA’s Chandra X-ray Observatory, is a very young and powerful pulsar, known as PSR B1509-58, or B1509 for short. The pulsar is a rapidly spinning neutron star which is spewing energy out into the space around it to create complex and intriguing structures, including one that resembles a large cosmic hand.
