What if oncologists did not study less lethal forms of cancer? What if they studied only lung and pancreatic cancer and declared the rest of cancer untreatable and unworthy of study as a result? This may sound ludicrous, but this is exactly what happens with the study of psychopaths. Academic researchers go to where they know they can find psychopaths: prisons. However, they did not include the possibility that there are psychopaths outside of prison walls because such field studies would prove “too hard”. This leads to a general picture of what the psychopath can do but not the complete picture of all psychopaths. If Kent Kiehl is right in his book, The Psychopath Whisperer, then 77% of psychopaths are in jail. This means that roughly 1 in 4 are not, however. Leaving 25% of any population unaccounted for is laughable, but yet we are expected to treat the prison psychopath as representative of all psychopaths. This is the result of nothing less than systematic failure when it comes to the study of psychopaths.
