As I've shared elsewhere, I do not believe this is a gendered issue. Please see the below addendum.
I believe indecision, conformity, and groupthink are behaviors that may be exhibited by any member of the species as secondary social strategies/behaviors to ensure survival by deferring power to another party.
My argument highlighted “women” being indecisive about dinner because I felt that the argument may come to a reasonable conclusion rather quickly.
Now, I realize it’s a relatively innocuous example of this phenomenon of indecision/agreeability (compared to the bystander effect, or how regular men became Nazis) and both stand by the example and wonder how to continue to write on the topic.

I think that besides survival strategies, there may be differences at the brain level, or the biological level which impact indecision patterns we see in women. For example I often have been amazed at how much hormones can influence women behaviors in totally irrational ways.
Are you suggesting that women make inferior choices based on some suboptimal design compared to male brains that has nothing to do with ensuring individual survival of the organism? Are you suggesting that female brains act in a way that is disadvantageous to survival by virtue of how they are designed?
I checked other studies to see what others say (and eventually conform myself to others) I found studies excluding gender in conformity studies. Based on that, I remain open to say it may be a bias, a definition problem, or erroneous conclusions based on biased observations I had.

I wouldn't frame it in a negative way, and I would avoid the term "choice" because we do not necessarily make rational choices, this is why I used the word behavior, particularly for groupthink. By the way is groupthink really the use of thought in a group, so is there a choice? Or could we characterize groupthink as an instinctive rally to a group?
So bottom line, I would tend to see women as behaving differently for biological reasons. Not inferior, nor superior, but tending to behave in a group differently than men. Am I wrong by stating that this impacts also conformity? According to some studies I checked earlier yes, however there could be multiple factors, like social, cultural, etc. This could explain why experimentally I saw differences between men and women during the period when people were wearing masks for example (using the word "experimentally" may be pompous since it is just observations based on everyday life).
