Suggestibility is something I try to avoid in outreach.

A friend was showing Omega Cent to a member of the public in the 18" Dob.
He mentioned that he could see an "Owl's face" in the cluster and asked the member of the public if he could too. "Yes", was their reply.

The seeing was too poor to see the face, suggesting being able to either made the visitor feel awkward that he couldn't or just bowed to peer pressure. A psychologist friend gave this human behaviour a name which escapes me.

Seeing thing which aren't there and having the brain fill in the details of a memory are everyday occourances.

Great topic glend!
