A new study published in Science (I became aware of it via Gizmodo) shows it could be possible to block the emotional recording of a memory. Lots of interesting possibilities for such a thing, but imagine if this were a pill and you took it prior to some religious event. The root of religious subscription is irrationality, in other words emotional appeal, and most proselytizing and apologetics target your emotions. Imagine if someone either has no emotional response or at least that response isn’t recorded into memory.
The joke about modern atheists is we’re like Vulcans or robots, cold and emotionless. Obviously that’s not true (I’m a prime example). The fact is some people are more successful at evaluating things objectively, minimizing any irrational influences such as emotions as much as possible. It’s not easy and can be very difficult at times. It demands commitment and strong will. For many it’s too elusive, so now there could be a pill.
I’m also thinking about this as a children’s chewable, perfect for those inescapable religious exposures like weddings, funerals, or random jackasses they may encounter at school holding prayers, religious assemblies, displays and what not. No pill yet for removing the need for religion, but this could be preventive medicine.
