My own experience suggests that whilst yes, genetics is an important factor in life outcomes, other things that are hugely important also aren't adequately researched, because genetic determinism is so widely accepted.

I've been experimenting with some self-improvement techniques for nearly 10 years. I found them after a few years of personal crisis and a quest for understanding, as I was very confused at what was causing my inconsistent life success/happiness/satisfaction/health. I'd had plenty of cases where I'd done well in life (in school work, career, friendships, relationships, sport, physical health) and plenty of other cases where I'd done terribly. "Trying harder" didn't seem to improve things, and in many cases made things worse. It didn't make sense that it was all explained by hard-coded genetics, as, well, it made no sense that my patterns were selected for by evolution, and it was hard to understand how genetics had given me a brain that was quite good at things one week but terrible at the very same things the next. And it didn't seem like these tendencies mirrored either of my parents'. It sometimes did seem like sometimes it was one parents' tendencies competing/conflicting with the other's, but other times the patterns seemed completely unlike anyone in my family. Genetic determinism just made no sense as an explanation, even after multiple doctors/psychiatrists said some version of "that's just how you're wired".

Just by chance I ended up connecting with a practitioner who practiced a form of "subconscious emotional healing", and whilst I was skeptical I was exasperated and open to trying anything at that point. After starting these practices, I felt immediate relief to a lot of the anxiety and fear I was feeling, and over time, all aspects of my life have gradually improved.

A particularly significant example of how this work has been beneficial has been in my career, and particular instances where I needed to learn a skill or deal with a challenge, and was finding myself very stuck, but by undertaking the healing work I was able to let go of the fear/anxiety/resistance I was feeling, then I found I was easily able to learn the skill or work through the obstacle, and have ended up being able to increase my capabilities and progress my career much more effectively. I've also been able to have a much better time with friendships, relationships, and my physiological health.

Some notable experts on the topic, such as Gabor Maté, assert that deeply held emotions like trauma influence our genetic expression, a mechanism known as epigenetics [1]. Others heavily dispute the role of epigenetics or the possible effectiveness of "subconscious healing" in altering life outcomes. It all seems to be derided as nonsense among conventional biomedical professionals and devotees.

The thing is, I don't see any significant research either proving or disproving anything in this area, but I do see plenty of non-mainstream practitioners and individuals undertaking this kind of work and having really good outcomes. I’ve often thought of trying to gather data on my own progress, of physiological indicators and perhaps even IQ tests, but it’s hard to get any meaningful testing done when you’re just a guy who reckons he’s onto something.

But it seems like an important thing to study, because, unlike genetic determinism, it has the potential to substantially change life outcomes for people living today. When I think about the times in my life when I was struggling, particularly as a deeply confused/terrified school student wondering why I was making my teachers and parents happy one week and disappointing them the next, and realise how much of it was influenced by the subconscious emotions that it's taken until now to identify and resolve, my heart breaks for the many people still experiencing those kinds of feelings, but believing or being told that they can't hope for anything better due to society's embrace of genetic determinism.

If anyone reading this happens to be working in fields related to epigenetics or behaviour-change, or is connected with anyone who is, and wants to talk to someone who has spent 10 years undertaking emotional healing work with great success, please feel free to get in touch.
