I don't disagree. I detest the use of my science as a means to control people for capitalist interest. The reality however is that regardless of the captualists, it would be a shame if we didn't understand how humans worked together.
Almost all the research we do indicates that the actions of the current economic system are harmful. Humans need to work less, have reasons to do things outside of money, have separations between their spheres of life, live with the basic psychological needs of autonomy, competence, and belonging met. If you ever support things like DEI or equal opportunity for workers, those are practices championed by IO psychologist.
We are no more captured by the capitalists as the chemist making a drung to save lives sold for the cost of a house, the doctor working 80 hours while his patients debts mount, or the computer scientist who wanted to build great things but can't afford rent if his paycheck wasn't from Lockheed martain.
I try my best to pull my science in a humanist direction. We are scientists, we can discover, we can advocate, but we can't prevent people from twisting reality to their whim.
