This "gender issue" never gets old.....and for some perplexing reason it frequently gets attention probably because people just don't think deep enough.
So, I want to say well done Prof. in conducting a more comprehensive study that reflects a more authentic result, significantly better than the study done by "social scientist" just like most other sociology based studies. (this is one of the major reasons I don't consider sociology a science, just due to its inherent subjectivity attached to it and frequent inconsistency in the interpretation).
So, congrats again Prof. in challenging, clarifying & dispelling fallacious "reasoning" of sociology based study.
On the whole, men don't like talking about problems because:-
1. Men are more suited and primed to solve problems, frequently look for challenges, so they prefer spending some time alone, quietly if possible, to reflect and analyze the problem, in order to find suitable solutions.
2. If it is a very stressful problem, men prefer "releasing the tension" by playing sports or to do any vigorous physical exercise. Like running or jogging as men like to "walk it off". Some men prefer to distract themselves with more work. Or even indulge in some high risk activities like drinking excessively, smoke, use drugs etc.
I personally can attest to most of these methods but wouldn't always recommend the last option, as it can easily cause a man to fall into an addictive behavioural pattern, particularly if the stress is caused by a major issue.
3. Men are inherently stoic and for good reasons because the ability to successfully control of one's emotion, helps men make more sound and reasonable decisions or judgements.
It's probably an evolved trait because masculinity is usually related to solitude, (just my own observation) because in Nature routinely males of various species spend time alone when not mating, while females always are in a herd. Also, routinely men handle stressful situation with "fight or flight" reaction while women use "tend and befriend" method and both are in keeping with our inner psychological sexual characteristics and behaviour.
4. In addition, studies show men prefer working with "things" as oppose to women, who like working with "people" and women are known to be more social. Also studies show, baby boys prefer moving objects while baby girls prefer faces. May explain why men are generally technically inclined.
All this comes back to the notable difference of masculine and feminine cognitive process whereby masculine is inclined to be logical, based on reason, perceives the world objectively, (LEFT brain dominance) while feminine nature emphasizes feeling, based on emotion and instincts, perceives the world more subjectively, (RIGHT brain dominance). Interestingly, homosexuality and I think transsexuality too, is more common in left handed individuals who are right brain dominance.
Probably, the reason why more men prefer science and mathematics subject compared to most women, a trend seen globally. This is another issue which is discussed routinely nowadays but lack proper reasoning. Discussion is always centered around discrimination and bias.
Perhaps, also the reason why women usually express more "emotional empathy" to someone in distress, shown by more 'direct emotional support' commonly via touch, holding hands and hugging while most men predominantly show "cognitive empathy" which is primed to find solutions to problems. This behaviour is also seen among chimpanzees.
I think that's why we men dislike asking other people for directions, and prefer figuring out ourselves but sometimes it ends up being a silly decision. (not male ego...haha).
Hence, when things are seen in wholeness, all the connections are observed, then, issues about differences in gender behaviours makes sense and appears more clear.
Be mindful, I usually say masculine and feminine because sometimes, not uncommonly, men can have certain feminine traits and women have masculine traits, the former is more common
Unfortunately, it is a popular notion nowadays, claiming men should not be stoic, communicate more and need to learn to have more emotions, I think this another rubbish idea, probably part of the "demonize & stigmatize masculinity" modern day misandrist agenda.
Personally, I have no problem with stoicism. I practice it and I know many other men sharing the same view. I am quite glad I have it as a trait because as mentioned earlier stoicism is a fairly useful skill.
Nonetheless, excessive and unlimited stoicism is a liability when it leaves us with a lack of emotional knowledge particularly in this modern day whereby stressful expectations in Life can be very overwhelming . For which I would advice men to occasionally catch-up with other men (good mates), to talk and share any problems over a meal and drinks. Others vital activities that help reduce stress is vigorous exercise, yoga and importantly meditation, offers heaps of help.
A good balance of mind & body in Life, to ensure a man's well-being will always a golden rule.
I have more interesting points but I will stop now, before people fall asleep.
Hope my "two cents worth" helped in some way. Cheers.
