I'm mainly referring to the 1950s through the 2010s, but I'm game to read anyone's interpretation of cognitive process(es) as they correspond to any particular decade!
Enneatype and MBTI and whatever else type-inputs are welcome too. It's just for fun.
I'll submit that the 2010s will be a decade of Ne-resourcefulness, followed by Si-stockpiling gratis the booming information age. So much data being hurled in all directions that needs to be multi-tasked and stored if proven useful.
