I love the recent experiments in neuroscience that are shedding light on the nature and origin of consciousness. I just thought of a cool test I would love neuroscientists to do if it hasn't been done already.
Imagine if instead of asking the subjects to flicker their wrist, or push between one of two buttons, why not have them viewing a hostage crisis and being put in a sniper's position where they have their hand on a mock gun with a trigger and they're asked to save a person who is being held with a gin to their head, and they have to either do nothing, or try to shoot the perpetrator in order to save the hostage. Then we can monitor their brain patters and ask them to acknowledge when they had the desire to kill the kidnapper, the same basic way we do in other experiments. This would be more challenging of course because the subject would have to be thinking about whether or not to shoot a kidnapper, and they'd have to try and remember to note what letter appeared on the screen at the time they thought of it. I'm not saying it can be done without problems but it's a nice idea to see if the same kinds of predictable signals occur before conscious knowledge of a choice when there is a moral factor to the decision.
