During the 1950s, Dr. Curt Richter from Harvard University performed a series of experiments using water, buckets, and both domesticated and wild rats which resulted in a surprising discovery within the field of psychology.
In the first experiment, Richter placed his test subjects into large buckets half filled with water with even those rats which were considered above average swimmers, giving up and dying within a few short minutes.
In the second experiment, Richter pulled each rat out just as it was about to give up due to exhaustion and let them rest for a few moments. Upon inserting the rats back into the bucket of water, Richter found that the rats continued to struggle to survive for up to 60 hours as the rats now believed that if they continued to push forward with enough effort put forth, eventually they would be rescued once again.
Richter recorded in his notes, “after elimination of hopelessness, the rats do not die”.
