Define Your Learning Goal: Competence Or Broad Knowledge

Is there a way to build broad knowledge for sight reading pieces, or is it merely a matter of sufficiently immersing oneself by just practicing?

What currents of thought on LessWrong do you want to see distilled?

Yes, I am quite hesitant to leap into the Sequences, not knowing how valid the studies cited are. I too would like to know how some of the mainstay LW concepts fare in light of the replication crisis (as psychology especially has faced a lot of problems in that regard).
