Passage Summary: Scientists often believe things because their famous colleagues do, but the writer says this is fine because everyone else in every other field does the same thing.

Conclusion: The fact that scientists are often motivated by social factors like prestige and peer consensus does not harm the scientific field.

Reasoning: Social influences are a fundamental part of every human activity, not just science.

Analysis: The argument is a classic example of a 'two wrongs make a right' fallacy, or more specifically, an appeal to common practice. The writer assumes that because social influence is ubiquitous, it must be harmless or acceptable within the specific context of scientific inquiry. You should look for an answer choice that points out that the prevalence of a behavior doesn't mean it doesn't negatively impact the objective goals of a particular field. Just because everyone does it doesn't mean it's not a problem for the integrity of the data.
