Just forget the Type 1 error thing.

A world of Wansinks in medical research: “So I guess what I’m trying to get at is I wonder how common it is for clinicians to rely on med students to do their data analysis for them, and how often this work then gets published”
It’s not just p=0.048 vs. p=0.052

Exchange with Deborah Mayo on abandoning statistical significance
My math is rusty
Deterministic thinking (“dichotomania”): a problem in how we think, not just in how we act
I think that science is mostly “Brezhnevs.” It’s rare to see a “Gorbachev” who will abandon a paradigm just because it doesn’t do the job. Also, moving beyond naive falsificationism
“Boston Globe Columnist Suspended During Investigation Of Marathon Bombing Stories That Don’t Add Up”
Question on multilevel modeling reminds me that we need a good modeling workflow (building up your model by including varying intercepts, slopes, etc.) and a good computing workflow

The status-reversal heuristic
“Here’s an interesting story right in your sweet spot”
The real lesson learned from those academic hoaxes: a key part of getting a paper published in a scholarly journal is to be able to follow the conventions of the journal. And some people happen to be good at that, irrespective of the content of the papers being submitted.
His data came out in the opposite direction of his hypothesis. How to report this in the publication?
He’s looking for a Bayesian book
My best thoughts on priors
Bayesian analysis of data collected sequentially: it’s easy, just include as predictors in the model any variables that go into the stopping rule.
“Bullshitters. Who Are They and What Do We Know about Their Lives?”
“Causal Processes in Psychology Are Heterogeneous”
“Any research object with a strong and obvious series of inconsistencies may be deemed too inaccurate to trust, irrespective of their source. In other words, the description of inconsistency makes no presumption about the source of that inconsistency.”
