Ronald Aylmer Fisher was considered an outsider by the statistical establishment of his time.
The links below (1-3) show his struggles & nuances with Karl Pearson, his son Egon, Bowley, their followers, and the Royal Statistical Society (RSS). His life was a story of accomplishments and noise (deceptions and nasty RSS politics). He was too ahead of his time.
That reminds me of the struggles of another maverick: Benoit Mandelbrot. Eventually and like Mandelbrot, Fisher greatness was recognized. Also like Mandelbrot, he was able to boost the signal-to-noise of his career and life.
Most statisticians consider Fisher the Father of Modern Statistics (https://en.wikipedia.org/wiki/Ronald_Fisher), even when he was not allowed to teach Statistics at the University of Cambridge (they tried to silence Fisher).
Yes, scientists too can be demeaning to other scientists, more for personal reasons than for ideas and the Scientific Method. After all, they are also mostly carbon units called “humans”.
