Kevin M. King @kevinmking.bsky.social · 20/06/20255) LCGAs also are very sensitive to lots of other things, like the time scale you study, what time intervals you select, or the scale of your data. psycnet.apa.org/record/2006-... psycnet.apa.org/fulltext/200...psycnet.apa.orgAPA PsycNet 1112
Kevin M. King @kevinmking.bsky.social · 20/06/20256) LCGAs never replicate across datasets or in the same dataset. They usually just produce the salsa pattern (Hi/med/low) or the cats cradle (Hi/low/increasing/decreasing). This has misled entire fields (see all of George Bonnano's work on resilience, for example). psycnet.apa.org/fulltext/201...psycnet.apa.orgAPA PsycNet 6294
