Richard Haier on the Neuroscience of Intelligence, Correlates of IQ, and the G-Factor

In this episode Curt Jaimungal talks with neuroscientist Richard Haier about the science of intelligence, the g‑factor, and how brain efficiency relates to IQ. They examine controversies such as The Bell Curve, discuss genetic and environmental influences, and explore interventions from brain training to neuromodulation.- 0:00:00 - Intro and book overview- 0:02:50 - Bell Curve controversy- 0:06:26 - Brain efficiency hypothesis- 0:16:06 - Stigma, race and IQ- 0:21:31 - IQ and morality- 0:22:27 - IQ vs g‑factor vs intelligence- 0:23:46 - Chronometry ratio scale- 0:26:38 - Low IQ as societal problem- 0:29:04 - Genetics and interventions- 0:31:18 - Brain training and nootropics- 0:31:55 - Dual n‑back- 0:33:17 - TDCS, PEMF and EM‑stimulation- 0:36:01 - Parietofrontal integration theory- 0:46:50 - IQ correlates with life outcomes- 0:47:47 - Character and morality tests- 0:49:16 - RAPM test demo- 0:53:24 - Path length between regions- 0:57:36 - Finn et al 2015 study- 1:04:12 - IQ genes probabilistic- 1:05:14 - Children IQ vs parents- 1:06:46 - Brain damage and savantism- 1:08:34 - Openness and intelligence- 1:09:40 - LSD trips and intelligence- 1:11:01 - IQ and happiness- 1:11:53 - Flynn effect limits- 1:15:26 - Factors that decrease IQ- 1:16:59 - IQ and consciousness- 1:22:00 - Mindfulness meditation- 1:23:27 - Joscha Bach on intelligence- 1:24:26 - Eric Weinstein on intelligence- 1:27:16 - Elon Musk Neurolink- 1:27:57 - AI and IQ tests for computers- 1:31:14 - Finding g‑factor in animals- 1:32:55 - What separates humansSPONSORS:- Patreon: https://patreon.com/curtjaimungal- PayPal: https://bit.ly/2EOR0M4- Twitter (Curt): https://twitter.com/TOEwithCurt- Apple Podcasts: https://podcasts.apple.com/ca/podcast/better-left-unsaid-with-curt-jaimungal/id1521758802- Pandora: https://pdora.co/33b9lfP- Spotify: https://open.spotify.com/show/4gL14b92xAErofYQA7bU4e- Google Podcasts: https://play.google.com/music/listen?u=0#/ps/Id3k7k7mfzahfx2fjqmw3vufb44- Documentary site: http://betterleftunsaidfilm.comRESOURCES:- RICHARD HAIER'S LINKS WEBSITE: http://richardhaier.com- BOOK: https://www.amazon.com/Neuroscience-I...
