If you want to learn how to learn, these two charts are where you should start. They are the result of a large meta-analysis of study techniques. You should skip the highlighting, summarizing, and rereading. Instead, practice, quiz & explain. Open paper: journals.sagepub.com/stoken/rbtfl/Z

Haha this is the famous paper. Hard agree on this.

He did his best to make sense of it. Yet I'm surprised why people I respect try to speculate on top of whoever pseudo science when science in this field is open, free, recent, verified and abundant.

I don't quite follow what you are saying here: can you elaborate? What are you referring to as pseudoscience vs. science?

1) successful #pkm course vendors are more marketing people than scientists. They take an insight and turn it into a keystone of science. No evidence, no research. We should stay very cirsconspect. 2) "metaresearch" is just another name for a patchwork of secondary research.

Understood re: (1), thanks! Though not-science != not valuable. I do like

's metric of believability for getting value: commoncog.com/blog/believabi Don't follow (2): did you mean meta-analysis? OP was that, not meta-research, which is diff. but also valuable IMO!

My philosophy is more based on doubt than belief :) Let's go for metaanalysis, did you read it? I scanned it. We are going backward in Learning science if we follow this reasoning.

Doubt less, rather than believe more? :) I didn't read it! Now that I have, I see I was mistaken: it wasn't a meta-analysis, but a narrative/critical review w/o specific methods for systematicity. Separately, curious what new developments you find compelling?

Good god, are you telling me that it’s NOT a meta-analysis? This is the second time I’ve read something by Ethan where he gets the fundamental results wrong (the other one was his thread on coffee, which was horribly done) I think I need to mute him.

(I clicked through. It’s not a meta-analysis. Wtf.)
