@doctorjaj @giladfeldman @drcpennington @OlegUrminsky Arguably its just the logical structure of multiple hypothesis testing. There's an earlier paper that I don't have to hand but this more recently: https://t.co/yo0Jh1NjjO
@Jake_Elder52 not correcting non-predicted main effects and interactions in an ANOVA for multiple comparisons "because the ANOVA already does this". No, it doesn't https://t.co/OVdbrmL6jo
@KouMurayama The logic is poor, basically. I really liked this paper: https://t.co/QzgarWOoYS
@GunnarBlohm @jjodx @BrianNosek Any guide should include multiway ANOVA, which is (nearly always) exploratory. The amount of times I have to comment on this in reviews is vast. E.g., https://t.co/vRoSpAPD0I
Podríamos responder "porque nadie lo hace". Pero eso no responde la pregunta de fondo: ¿aumenta el error del tipo 1 (falso positivo) en este caso? La respuesta la podés encontrar en este paper: https://t.co/vGhKvdEEQJ

@Samcox301 That p = 0.036 would not survive corrections for multiple comparisons: https://t.co/zJcQVh0Kqi - so another likely explanation is that it is just a fluke. Interpret with great care - it might just be noise.
@CForestier_PhD @lakens Aaaand I’m wrong haha. https://t.co/2g5zIzyE4V but I think you’ll find your answer here.
@Saffello96 the only case i can imagine is if this particular test was decided upon a priori, but it was one of many other similar possible tests which were NOT decided upon a priori. Cramer et al make such a case for multiple testing in an ANOVA. http

@seriousstats @PaulMinda1 @timmytimmytim I really like Cramer's (2016) approach. Only use the ANOVA-test results you predicted (i.e. the specific interaction) and then Bonferroni-correct all others. https://t.co/OVdbrmL6jo

@BecketTodd @minzlicht Don’t forget that this will increase the experimentwise error rate 👇🏻 it’s an often overlooked issue in multifactorial anova. I hope the link helps! https://t.co/KhDsayuIgv
@BecketTodd I don't think n=24 is underpowered in principle, could be ok for large enough effect sizes. But the lack of multiple comparison corrections is a problem, unless specific interaction is predicted. I would ask for Bonferroni correction based on C
@lieberothdk @lakens @angecramer If you look at the PS to my blogpost there's a couple of references https://t.co/mXdJeWL4HA We all rejoiced when the Cramer et al paper came out as it does provide a clear account of the problem that one can cite https://t.

@PsychScientists I don't quite understand why the researcher is even performing a 3-way ANOVA if the preregistered hypotheses are at all the 2-way level, but regardless any such 3-way interaction should be treated as exploratory. See this @angecramer @EJWa
@sTeamTraen @laura_vowels @lakens @LorneJCampbell but they very rarely correct for multiple comparisons within a multifactorial ANOVA. e.g. in a 2 x 2 x 2, there are 7 tests (the main effects and interactions) that are not corrected in any way. See https:/

ANOVAs do not really control the false error for multiple comparisons: https://t.co/9rNST0kABp - see also: https://t.co/l3qDaXs7Dn There are really not a lot of reasons not to use mixed models.
