Lately, I've been writing about the social realities of violence, power, and change in the perspective of social psychology.
In the evolution for example of the theories of leadership, we find out that recent studies always showed the veils of the ideology of the older theories embedded in the conclusions.
Scientists are always influenced by the ideologies they have, that contaminate results of their investigations.

Much empirical research supports the idea that ideology dominates social psychology
Much of social psychologists are liberal and explicitly report negative attitudes towards the conservatives, but in my point of view, we must keep the diversity of opinions to avoid the negative effects posed by political homogeneity in scientific validation.
I'm a social psychologist myself and in every study, I made I always tried to clean up my political biases, because, for example, I hate all politicians and the big capital.
