@cremieuxrecueil The most aggravating part is that he didn’t even understand what the problem was himself

[Lau Holgersen @laabho]

@lakens @johuellm Do you know of any papers that study how often robustness checks support the main hypothesis? Might be interesting to look into

[Daniël Lakens @lakens]

I am hiring a PhD student on the meaningful interpretation of effect sizes as part of my VICI funded project. This is a 4 year paid position in a welcoming and collaborative environment. Find out more or apply at https://t.co/ftWYg2yxIy

New paper: Blaming the Thermometer for the Fever: Separating Misapplication from Method in Null Hypothesis Significance Testing, with @laabho and @jesper_wulff . We - strongly - push back on criticisms against NHST, and argue for its proper application. https://t.co/RtIlZJUHx4 >

[Lau Holgersen @laabho]

@matloff @lakens @jesper_wulff I see where you are coming from, but the binary structure of NHST is a feature, not a bug. It does not ignore uncertainty... it manages it through predefined error control. CIs serve a different role in summarizing estimation uncertainty, not guiding decisions.

[Lau Holgersen @laabho]

New preprint with @lakens and @jesper_wulff:
"Blaming the Thermometer for the Fever: Separating Misapplication from Method in NHST"

NHST gets a lot of blame—mostly for issues it did not cause!

Read it here: https://t.co/b6eXD0cu8W

[Lau Holgersen @laabho]

@matloff @lakens @jesper_wulff (a) Measurement error affects all estimates.
(b) A p-value is a probability statement, not a decision rule. It only “usurps” the analyst role if allowed.
But you should read the paper; we do not claim NHST as the only useful methodology

[Lau Holgersen @laabho]

As promised, the preprint is now out:
"Blaming the Thermometer for the Fever: Separating Misapplication from Method in NHST"
We push back against calls to ban dichotomous testing and defend error control—properly applied.

[Daniël Lakens @lakens]

We will soon post the corresponding preprint 'Blaming the Thermometer for the Fever: Separating Misapplication from Method in Null Hypothesis Significance Testing' which pushes back on the idea to ban error control in science by not allowing dichotomous tests.

@Afinetheorem Good thread! No need to manually maintain a .bib file—use a reference manager like Zotero. Just add a DOI or ISBN, and it will fetch all the right details. You can share reference lists with coauthors, and it integrates seamlessly with Overleaf

[Lau Holgersen @laabho]

@intuitidbits Is this really what anyone would consider an acceptable DAG? I see absolutely no convincing argument here directly linking low RHR to aggression… I do see copious amounts of selective reporting though

[Lau Holgersen @laabho]

@ajordannafa It’s not entirely arbitrary though… but yes, using more stars for a larger alpha is the real crime

[Lau Holgersen @laabho]

@RexDouglass But using smallest effect size of interest to test against clearly shows that it is not a made up concept to sell power analysis… clearly it serves other practical purposes

[Lau Holgersen @laabho]

@RexDouglass To be fair, any concept in statistics is made up. Besides, smallest effect size of interest is useful for other things than power analysis… for example to test against instead of null thus providing a more severe test

[Lau Holgersen @laabho]

@CharlesDriverAU @lakens @J_A_Quent But why would you want indirect error control when alpha offers a direct, and as you point out, standardized way of achieving this?

[Lau Holgersen @laabho]

@RexDouglass Gelman aside, it seems to me that the three main points he makes are completely fair and not mischaracterized, shallow or creepy as you postulate. In fact this very blog is about dichotomous choices.

[Lau Holgersen @laabho]

@andrewgwils @lukaemon Quite the conjecture… if used to point out flaws, discrepancies, grammar mistakes, or propose better structure, rather than simply creating content, wouldn’t it only make you a better writer in the long run?

[Lau Holgersen @laabho]

@RexDouglass What does he say in the blog that makes him seem like a snake oil salesman?

[Lau Holgersen @laabho]

@larsgade @P1radio @EsbenBjerre Hvis det kun er landmænd, der må udtale sig om landbruget, så sætter vi lidt ulven til at vogte fårene, gør vi ikke?

[Lau Holgersen @laabho]

@schneider_jw Og derfor burde equivalence tests være meget mere udbredt... Desværre er det sjældent noget, man ser.

[Lau Holgersen @laabho]

@Perpetualmaniac The ability to extrapolate is a blessing and a curse
