I read somewhere (truly forgot where, sorry) that we humans are mostly just lazy, that we avoid thinking as best as we can and rather gravitate towards that (people, circle, or news) which confirms what we already believe so that we do not have to think.

"Confirmation Bias" does not quite capture it. Really just laziness. :)

The other part, being decisive... I can definitely relate to that. I noticed that I often have a hard time making decisions and realized it's because I tend look at the world in terms of what I can possibly lose instead of looking at something new in terms of excitement.
