Dr Tomas is a psychologist who carried out research or almost a decade between people's perception on their abilities and their true abilities to do something in 40 nations across the world. Interestingly, he found there were least relations between confidence and competent. He also pointed out that up to 70% of people is overconfidence. There are two personal benefits of being overconfidence based on recent psychology publications and motivation books. First, it is feel good for people to imagine themselves as an outstanding person and secondly, these misconception may useful to help others.
However, Dr Tomas revealed that there are several dire effects of overconfidence such as gamblers and people who miscalculate their ability to pay loans and mortgage.
