So, I met this friend INTJ of mine at a time I was very obsessed with intelligence. It was the center of my life. I scored about 2,5-2.8 standard deviations up from the norm. I hadn't found many people like me. I met him, and he was 3.0-3.2 standard deviations above the norm, so about 0.5 std devs. I understood the intellectual pecking order was him on the top, me below. I've heard from more than a few people it's the other way, but I was IQ test religious back then.
He went on to pursue a career in academia. I sought him to be a friend supporting my intellectual pursuits, I hoped we could do some of them together. I wished he would have been my peer. I had moved from university studies (on the same field of study) to work after a few years and gathered street smarts. He, none.
We talked about mathematical modelling methods to reduce the time & space complexity of the calculation of sound propagation in architectural structures. He told about a few models, we discussed. I suggested a model that would make an aural "holograph" of a facet in an imaginary 3d structure, modelling the 3d space as an in-out function of the sounds going in and out. It was a novel finding, as none of the previous work suggested making a 2-dimensional image of both the phase and the amplitude and applying it to that context.
The thing is. Hmm. Well. He neglected the idea when he spoke about it. Lured me to tell my ideas of it. In the end, it wasn't supposed to be much anything. He used his authority I had given him to dismiss my ideas as not very worthy.
Half a year after he described a novel method exactly like the one I had described. No mention of my contribution to the subject. He had taken the idea as his own. In a way, I didn't mind. I'm not seeking the favor of the same academic people. But, in a way it hurt. Is he becoming another professor who just finds the brilliant ideas his students make and takes them in his own name?
I learned not to trust him too much. He's somewhat of a friend. Good friend, even, or okay, borderline. But.
He writes dozens of papers. He has years of more education than I. Our friendship hasn't been the same after I understood him using my ideas without proper credit. That's about the worst as it comes in academia.
What's so bad in giving credit to someone who's worth it?
I'm disappointed to be treated as just another person to be "gamed", especially when he tries to portray an image of intelligent but socially weak person, possibly someone who couldn't abuse his relationships.
