Coffee makes us say 'yes'

ABC Science reports:

If you want to bring someone around to your way of thinking you should make sure they've got a cup of coffee in their hand, according to research showing that caffeine makes us more open to persuasion.

The Australian researchers say a caffeine hit improves our ability to process information and increases the extent to which we listen to and take on board a persuasive message.

They tested this by quizzing people about their attitudes to voluntary euthanasia and abortion before and after either the equivalent of about two cups of coffee or a placebo.

They were also given a persuasive argument to read after having the caffeine.

The experiments showed that "caffeine increases persuasion through instigating systematic processing of the message".

So if you want to brainwash someone, then give him a cup of coffee first.
