The Economist says becoming a great investor often depends on more than skill, pointing to a mix of luck and personal temperament. It argues that consistently strong outcomes are difficult to attribute solely to strategy, with chance playing a significant role.

The outlet also highlights that successful investing is associated with “nerve” and unusual personality traits. Rather than portraying investing as purely analytical or rule-based, The Economist frames it as a discipline that tests how people react under uncertainty—suggesting that individual character can influence decisions when markets move unexpectedly.
