Researchers often distinguish between:
1⃣ Exploratory hypothesis tests - unplanned tests of post hoc hypotheses that may be based on the current results, and
2⃣ Confirmatory hypothesis tests - planned tests of a priori hypotheses that are independent from the current results
1⃣ Exploratory hypothesis tests - unplanned tests of post hoc hypotheses that may be based on the current results, and
2⃣ Confirmatory hypothesis tests - planned tests of a priori hypotheses that are independent from the current results
This distinction is supposed to be useful because exploratory results are assumed to be more “tentative” and “open to bias” than confirmatory results.
We challenge this assumption and argue that exploratory results can be more compelling than confirmatory results.

Bearded men more likely to be sexist. It's science!

How did they find that out?
By doing analysis until p < .05.
However, not everyone is this honest about the reporting. Most researchers don't tell you all the steps that led up to the magical number .05.

What about replications?
They found nothing, of course.

Thrilled and proud that @PNASNews published our study Today: The Diversity-Innovation Paradox in Science. Find it here: pnas.org/content/early/…. GitHub: github.com/bhofstra/diver…. Short primer: bashofstra.com/diversity-inno…. 1/n
Study by myself, @viveksck, Sebastian Munoz-Najar Galvez, Bryan He, @jurafsky, &Dan McFarland. We study the diversity-innovation paradox: Diversity breeds innovation, yet underrepresented groups that diversify organizations have less successful careers within them. 2/n
Does the diversity-innovation paradox hold for scientists as well? To answer this question, we use text analysis and machine learning as well as US census and dissertations of more than 1.2 million recipients of doctoral degrees from 1977 to 2015. 3/n
Here's a little 101 on what happens in behaviorism (ABA). Behavior analysts set themselves up as the authority in science and against what they call "pseudoscience." These people are sharing this article as "evidence." Look at the article: news.fiu.edu/2019/weighted-…
At first the article didn't even name an author, but after complaints, it has been added. The article asserted originally that ADHD meds were not effective. That has since changed. It also asserts that it's the first to study weighted vests and activity ball chairs in classrooms
It talks about how much money is spent on OT in classrooms. Same financial fear-mongering as they always use. As "The Usual Suspects" of alt-autism use to talk about the "epidemic rise" of autism to ask for more money to go into eugenics and behaviorism.
Now panel “Intelligence + Agency = Free Will” moderated by Jennan Ismael #FQXi2019
Do we have free will?
Sara Imari Walker: Something is missing in our understanding of physics needed to explain origin of life (my research) and free will. But yes.
