Scientific research in the 20th and 21st centuries has continued to struggle with the same basic questions about human behavior. Are we products of nature, nurture or self-volition? In other words, can we attribute our behaviors/strengths/defects to biology, the environment we grew up in or our own efforts?
A growing body of research seems to suggest that we are products of all of these influences and more. But this leads to other questions. If we are shaped by factors beyond our control, can we take credit for our successes? And how culpable are we when we commit crimes?
