I don’t think anyone’s arguing for speed over domain expertise. But all else being equal, iterating more quickly is an obvious advantage. You get more chances to correct mistakes and adjust to new information. Your decision may be to continue with the same strategy, but having the capacity to make that decision is important in itself. Take fencing, for example. At low levels, people often try to make up for poor technique with speed and strength. Like you point out, this is a mistake. But at the highest levels, where everyone’s technique is basically flawless, the winner is the fencer whose thinking is a step or two ahead. That said I’m really talking about situations where you have an active opponent. With more static problems yeah, being correct is more important than staying on your toes.
