Self labeling by some as scientists.
Last few years I ran into several folks, all in the chemistry business of sorts. A few working on AA, a couple working on or having BS, one with MS degree in various areas of chemistry. They all referred to themselves as scientists. Frequently.
Seems a bit presumptiuos and uppity.
My early encounters with scientists were Phd holders in physics, math, geophysics, oceanography, marine biology, geochemistry etc.. I w*rked for and with a few dozen. None ever called themselves as scientists, they were noted as such by others.
