user64500: I have a question about my Biology Stack Exchange post: Is there any biological/psychological reason why women find men's chests attractive?
In just 25 views, you can see 7 downvotes. But when I had asked opposite, I mean men's interest in breasts, I have 4 downvotes so far in 118 views. And those 4 came before the significant edits in question. Not after that.
So why is this biased response?

user27148: Guessing causes for downvotes can be fraught with peril, but I'll give it a shot:
For your first post, people may have thought the question was not well-posed, but didn't want to give discouraging downvotes to a new user asking their first question.
For your second post, some of those same people may have seen you've now asked two related questions, and didn't feel like your second one incorporated the feedback from the first and made some of the same mistakes. In this case, they were more free with the downvotes
Also, views are not a very good comparison measure. They include multiple views from the same people, and you've posted about your question on Meta and there have been some edits and some comment discussions - likely people including yourself have refreshed that question several times, incrementing the views, but people can only vote once.

user59521: What you seem to be implying is that the reason for the downvotes is the political correctness, biased in favor of women. While this is not to be excluded, there are many confounding factors that that make such a straighforward conclusion suspicious. I list a few reasons why the numbers of votes could be different:

The two questions are clearly rather different in their content, so it might be that one simply appears more scientific than the other.
The questions might have not been presented to the same audience - there is significant variation in terms of how many people look at the sight at certain time of the day, week, school year, etc.
Some votes may result from a person simply being in a bad mood - a PhD student who has just had an unpleasant conversation with their professor, or the professor who makes a break between two lectures to  not-so-bright students.

Remark
If we take as a null hypothesis that the two posts are downvoted with the same probability, then we could use binomial test to check this hypothesis:

Estimate probability for the "male chest" post:
$f=7/25\approx 0.28$. The probability that you get $4$ or less downvotes on the "female breasts" post is then:
$$
p=\sum_{n=0}^{4}{118 \choose n}f^n(1-f)^{118-n} = 2.81 \times 10^{-12}
$$
Conversely, if we estimate the probability from the latter post as $p=4/118\approx  0.34$, then
$$
p=\sum_{n=7}^{118}{25 \choose n}f^n(1-f)^{118-n} = 1.44 \times 10^{-5}
$$

In both cases the null hypothesis can be rejected, but, as I explained, there plenty fo reasons why it may not hold. may
