In college I participated in a psychology experiment being conducted by a mate who was majoring in it. He told me it was a “memory test.”

They show you hundreds of images/words, then another batch asking if you remember seeing these in the previous batch. I asked how I scored.

He told me the test was really about “false memories” — they were looking to see if they could induce [false] recall of images/words never shown.

He said my results were “unusual”; in his testing of hundreds of subjects, apparently I was the only one who did not recall a single ‘false’ image. An outlier.

At the time I attributed it to my pre-college life as a paramedic. I was well trained to be certain of my observations and measurements. If you can’t verify your assessment, you don’t guess. Ever.
