Can we think too much for own good sometimes? The answer, according to this new study, is yes. Worse, if you are not careful, manipulative salespeople can use this tendancy against you.
According to the study, the more complex the decision, the less useful deliberation becomes. Therefore, a smart salesperson sensing your gut is telling you "no," might instead encourage you to deliberate on the pros and cons. Of course, this might seem like common sense but if you arrive at a decision opposite of your initial reaction, you will probably come to regret it.
