Fear or Hope, You Decide

Over interpreting results and sound bites in science are dangerous but seem to have become the norm. A Linked-in post that my husband chanced upon was inferring about the power of “hope” from a rat behavioral experiment. My husband read the post aloud (taken verbatim from the post)- “An interesting Brutal experiment was conducted in the 1950s by a scientist named Dr. Curt Richter. In that experiment, he took a dozen domesticated rats and placed them into jars half-filled with water to test how long they could tread water. Unsurprisingly, the rats drowned, but the idea was to measure the amount of time they swam before they gave up and went belly up. On average they’d give up and sink after 15 minutes. But right before they gave up due to exhaustion, the researchers would pluck them out, dry them off, let them rest for a few minutes — and put them back in for a second round.

In this second try — how long do you think they lasted?” continued the blog.

My husband turned to me and repeated the question, how long did I think the rats lasted. I know well about behavioral tests such as the “forced-swim test” or the Morris water maze test but without further context about the experimental design by Dr. Richter, “learned helplessness/stress” popped up in my mind. And hence my response was that the rats “gave up” rather quickly. You see, most of these behavior experiments have a pre-training session, based on the question asked and I wasn’t sure what question was being interrogated. To my surprise, my husband read on “Remember — they had just swam…
