  I agree. Summary of findings: “Test subjects who spent hours practicing [insert proprietary game here] scored better when tested on different games that require similar skills.” Smells like a poorly designed experiment salted with commercial interests.

    That's vague. Do you have specific examples of flaws in methodology or analysis in the published peer reviewed results here [1]? [1] https://www.frontiersin.org/articles/10.3389/fnbeh.2019.00002/full https://www.frontiersin.org/articles/10.3389/fnbeh.2019.0000...

    Yup. A similar thing happened with a training/game called the "N-back" test that allegedly could improve executive function and IQ! Turned out the test of IQ was Raven's Progressive Matrices and it's never been decisively validated https://en.wikipedia.org/wiki/N-back#Use_in_tutoring_and_rehabilitation https://en.wikipedia.org/wiki/N-back#Use_in_tutoring_and_reh... https://hn.algolia.com/?query=n-back&sort=byPopularity&prefix&page=0&dateRange=all&type=story https://hn.algolia.com/?query=n-back&sort=byPopularity&prefi...

      Dual N-back is reported to improve working memory, which can help improve IQ. A excellent report is here https://www.gwern.net/DNB-FAQ https://www.gwern.net/DNB-FAQ

        That's great except Dual N back is, at least for me, impossibly hard to play. And I have in my estimation a good working memory that enables me to work on multiple abstraction levels simultaneously without losing track. Are there any tips on how to not miserably fail?
