This book introduces ten great psychological experiments by brilliant psychologists and psychiatrists of the 20th century that astonished the world with hypotheses and theories about human psychology and nature, such as "What is a human being?" and "What makes a human being human?"

The author unfolds ten experiments in narrative form, questioning their current significance for the world we live in and reexamining them from a contemporary perspective.
'What does Skinner's behaviorism, which states that human behavior is determined by reward and punishment, mean to today's neurophysiologists who study the neural correlates of habit-driven rats?'


The author introduces readers to the background, context, and implied meaning of the experiment through vivid narratives that include interviews with experimenters and personal experiences.

More interesting than the relationship between altruistic acts of helping others and time is the relationship between group size and time.

However, Dalley and Latane's experiment challenges the evolutionary theory that larger groups lead to greater security.
The idea is that helping behavior is inhibited by the bystander group.
