I think you have hit on why AIM is sometimes difficult to follow for most people. It goes against the "herd mentality" which is the most comfortable method of investing.
Comfortable emotionally, uncomfortably financially Any means to 'correct' emotional behaviour (i.e. AIM) - helps to promote financial benefit. Consider the effect of taking the opposite stance to the 'average' investor (buying from them when they are selling, selling to them when they are buying ("buy from the scared, sell to the greedy" is one of Tom's old sayings)).
