83 Percent of Radiologists Didn’t Spot the Gorilla Hiding in This CT Scan

Interesting!

What can we learn from the experiment? Well, the point isn't to admonish radiologists. Rather, the test was designed to investigate whether being highly trained made people less susceptible to the phenomenon of change blindness. Clearly, it doesn't.

The gizmodo article is wrong that it mentions "change blindness", because this is not "change blindness" but "attention blindness".
Change blindness occurs when we don't notice small changes to an image due to bigger changes happening (e.g. image flash between the changes).

Still, I hope my CT scan never shows up a gorilla....

Trained radiologists / radiographers etc. tend not to look for or see zoo animals in the imagery they review - or in clouds. Laser focus, they have.

That was my thought too.
Had it been a copyright notice, or any other human made artifact, the mind just passes by the thing that does not pertain to the problem at hand.

I forgot the exact percentages in the experiment I'll describe. I read about it in a book "Ich weiss was du denkst" (I know what you think in German).

They asked people whether they consider themselves lucky or unlucky. Then all people were given a newspaper and asked to count number of pictures in it. In the middle there was an add saying "Those who inform the leader of experiment about this add will be given 100GBP."

Most people who considered themselves lucky noticed the add while most unlucky-ones didn't.

... and the postal service doesn't look at the street address anymore, I call it inept blindness.
