I am not a type 3 engineer myself but I too believe it's a matter of mindset. So what you want to do is to help them change their mindset. I have read 2 really, really interesting books on that matter. The first is called 'Mindset' by Carol Dweck and the second one is 'Talent Code' by Daniel Coyle. They are so valuable I believe that from now on we will see a blossoming of talents in the western world never seen before due to such books addressing mindset problems. I hope you take the time to look into them. They will give you hints and advice on how to spark the growth mindset in other people.
I was introduced to the Dweck book some years ago and it made a big impact on me; I essentially had a fixed mindset and needed to "see" it in order to change it. Another really good book is Mihaly Csikszentmihalyi's "Flow", which, for me, anyway, extends Dweck's growth mindset concept to an operational level. I have recommended both numerous times to good effect. I'm not so sanguine about the blossoming of talents; our system of education does not encourage the growth mindset, for the most part, until it's too late and learning it later in life is hard.
