Popularity Can Indicate Utility

The original idea correctly points out that widespread belief in an idea does not make it factually true. History is full of popular misconceptions that were later debunked. Popularity is frequently driven by cognitive biases rather than empirical evidence. However, dismissing popular ideas solely because they lack scientific rigor overlooks why they spread in the first place: their functional utility. Evolutionary anthropologists, such as Joseph Henrich, argue that cultural beliefs and practices often survive because they confer a survival or coordination advantage, even if the explicit reasoning behind them is flawed. Many cultural myths and simplified mental models are technically inaccurate, yet they survive because they help people navigate complex environments or build social cohesion. They act as adaptive heuristics rather than objective truths. A forking system allows us to acknowledge that an idea might be scientifically false but functionally useful. We don't have to choose between total acceptance and total rejection. We can separate the truth value from the utility value. Instead of merely debunking popular beliefs, we should examine the psychological or social gap they fill, and build better models that address those same needs without relying on factual inaccuracies. The assumption behind this fork is that the survival of an idea in a population is driven more by its adaptive utility than its objective truth.
