Curt Richter

in 1950, Curt Richter, a university professor, conducted a spooky experiment with rats to study how long they could survive before drowning.
First he took a dozen rats, put them in glass jars, filled them with water and watched them drown. The jugs were very large, so they couldn't hold on to the sides, or jump out.
On average, they stopped resisting after about 15 minutes.
But then Richter turned his experiment around.
Just before they died of tiredness, the researchers took the rats out of the jars, dried them and let them rest for a few minutes to put them back in for a run-off.
How long do you think the rats lasted? Another 15 minutes? 10 minutes? ¿5? No, 60 hours.
It's not a mistake, the rats swim for 60 hours.
The results showed that after "saving" the rats just before they drowned, it caused rats to swim approximately 240 times more when put back into the bottle.
There was a rat that swam for 81 hours.
The bottom line is that the rats thought they were going to be rescued, and that's why they continued to swim to a level previously thought impossible.
This story is often explained in positive psychology as an example of the importance of "hope and optimism."
It is obvious that most people can do more when they receive encouragement or stimuli, and stop or abandon when they have no hope or sufficient appreciation.
