Look I’m going to end this discussion after this post because this discussion is more about Dual N back rather on whether people can be trained or not.
You’re taking this whole discussion way out of context I’m afraid. I never said that innate skill is more important than hard work and strategy. My point was that there is a limit to what you can teach in life, just like there is a limit to having a large IQ.
You keep interpreting everything in such an extreme way! I’m not in any way trying to say that people are destined to fail or succeed based on their IQ tests!
Genetics, education, and hard work all count towards success. Perhaps hard work and education can have a more profound impact. However, if you compared two people with identical level of education and hard work ( and other factors that are equal), but with different IQs, it may be that the person with a greater IQ might be more likely to do better. In life, this may not happen of course due to either luck, varying levels of hard work, and other events ( stress, family issues).
No-one is a bigger proponent of hard work than me - this is evident by the fact that I’m trying to learn 100 different techniques to try and improve how I study ( which is why I’m here on this forum!). But you cannot simply shut your eyes and avoid reality. Genetics does play a part - it is not the “be all and end all” and I never suggested it was. I cannot control genetics, but I can control my hard work and my education, and I’m doing that.
My observations on engineering are based on having about 20 friends who are mechanical engineers and their own comments. There are also my two uncles who have been mechanical engineers who shared information from their 20 and 30 year careers respectively. They all agree that mechanical engineering is a more problem based subject versus medicine which is relatively more knowledge based. You can be a perfectly competent engineer with moderate talent and extreme hard work, but those at the top of their field are generally very talented AND hard working.
Out of interest, what do you study?
