Passage Summary: Just because natural scientists use math to predict things doesn't mean social scientists should, because doing so would ignore important details and mess up the results.

Conclusion: Social scientists should not attempt to achieve predictive power by reducing social phenomena to mathematical expressions.

Reasoning: Using math in social science would result in the loss of important non-mathematical data and lead to a distorted understanding of social reality.

Analysis: To find the conclusion here, look for the author's pivot against the social scientists' assumption. The word 'But' in the third sentence signals the author's main claim: that performing this mathematical reduction would be a 'mistake.' The subsequent clauses explain why it's a mistake, making them premises. Focus on the prescriptive claim that social scientists ought not to follow the natural sciences in this specific way.
