Do you recall when you last read in the newspapers about how someone convicted of murder has their searches used as evidence against them?

What comes to my mind when I read this is what the base rate of suspicious searches is. If 10% of days include at least one suspicious search in the base population, the value of such a search as evidence of malice is greatly reduced. But most people don't consider base rates.

On the topic of the differences in parents' concern for their boys vs their girls, for genius vs overweightedness, there's a simple rationale: for future career and relationship success, a boy's intelligence and a girl's looks are relatively more important than vice versa. It's not right or fair, but it's believed to be true, and that's what makes people search for it.
