Scientists observed entrepreneurs running high-technology companies around Cambridge and found that they exhibit more "highly adaptive risk-taking behaviour" than their more cautious corporate brethren and that this can result in far more positive results during stressful business situations.
It also suggested that as risk-taking and quick decision-making were linked to the neurotransmitter dopamine, there is a possibility that drugs could be developed that the naturally risk-adverse could take.
Professor Barbara Sahakian, lead author of the research, said the findings "raise the question of whether one could enhance entrepreneurship pharmacologically".
"Entrepreneurs can be taught - it's a mindset. Change your mindset and the world will open up," he said.
