This io9 post reviews the science behind a couple of studies of an experimental anti-fear drug, at Duke University and the NIH: "The common element in their studies is a gene-encoding enzyme called fatty acid hydrolase, or FAAH. This enzyme breaks down a natural endocannabinoid chemical in the brain."
The conclusion? "This discovery suggests that those people who are not endowed with the lower enzyme function could be treated pharmacologically to modify their fear response."
There are pros to this potentiality, of course: "The fear-reducing pill could be seen as a kind of nootropic, a next-gen sort of cognitive enhancer. It may allow people to pierce through their anxieties and reservations and engage more deeply in life and their passions. It could even help people with stressful jobs, such as police officers, firefighters, soldiers, and athletes."
There are also cons: "It's worth noting that psychopaths have an impaired amygdala."
Bonus SNL Point-Counterpoint video, starring Dan Aykroyd and Jane Curtin.
