I don’t know if this is a well known theory or not, but the basis is that it’s impossible for someone to be unbiased, even if they say they aren’t. People are subconsciously biased to a degree, so it’s impossible to be truly unbiased.
I doubt this has any substance, but I thought it was an interesting thought experiment.
I agree here. First, the idea of being cognizant of your biases can allow a potentially more unbiased opinion. For example, when consuming news media, one can recognize their preferred outcome, and perhaps spend some time getting “the other side of the story.” I’ve found doing so actually helps clarify certain issues or events, as the common thread between the two stories tends to be where the truth lies.
But there’s also the inherent desire for us to advance or evolve as humans. Bias isn’t necessarily “bad,” since that seems to indicate we’ve settled on something we think provides a net positive to ourselves or the species. It turns bad when we’re not willing to acknowledge the possibility there’s a better way.
So, I guess to sum it up, out the gate, I don’t think one can be truly unbiased, but I think one can learn the ability to make decisions with equal preference for both decisions. To live in a world of only bias is, imo, akin to evolutionary stagnation.
