There is a highly instructive symposium on "Veil of Ignorance" #ProcessTracing in the new @APSAtweets QMMR publication https://t.co/nxqEQ9HaRz There is lots to say ab it. For now, I want to focus on whether (causal) qualitative research has a problem w/ confirmation bias that 1/

needs to be addressed.
In short, Veil of Ignorance process tracing aims to blindfold the data collectors and analysts to the hypotheses to reduce risk of confirmation bias.
Proposal receives a lot of criticism by all respondents, partly for valid reasons, partly not, IMO 2/
If there was no bigger issue with confirmation bias, there would not be much benefit in talking about blinding in qualitative research.
As Beach notes, the intro to the symposium does not present evidence that bias is a problem. This is correct, but there is also no evidence 3/
that confirmation bias is not a problem. It's an absence of evidence situation with regard to comprehensive, direct evidence, i.e. from verification studies of qualitative research (for studies that are built on an epistemology for which the idea of verification makes sense). 4/
However, I'd say there is circumstantial evidence that confirmation bias is a problem.
1) Evidence for confirmation bias in quantitative research: The developments around #OpenScience and transparency in quantitative research in different disciplines present diverse evidence 5/
for confirmation bias (aka as publication bias).
- Selective reporting/underreporting: https://t.co/qB87qwzuRj
- Unusual excess of positive results: https://t.co/GcdkQhCNhV
Could it be different for qualitative research? Unlikely. Publication bias, whatever its source, 6/
creates an incentive for positive results because careers, funding etc. depend on getting published. I don't see why the same incentives shouldn't apply to qualitative researchers (more 👇). I neither find it plausible that researchers who are less susceptible to these 7/
incentives select themselves into the application of qualitative methods.
2) Publication bias in qualitative articles
@alan_jacobs1 has published a terrific book section on transparency in causal qualitative research https://t.co/EsQmIJrImN It presents clear evidence for 8/
publication bias in qualitative research. This is not direct evidence for confirmation bias in these articles bc it could also be that articles w/ negative results are filtered by peer review. However, it is a sign that confirmation bias could be an issue. 9/
3) A partial reassessment of Moravcsik's 'A Choice for Europe'
Lieshout/Segers/van der Vleuten presents a reassessment of a specific part of Moravcsik's monograph 'A Choice for Europe'
https://t.co/HRLpW6ylTo
I find this article is an excellent illustration of how one can 10/
verify qualitative research. Their reassessment points to a couple of problems with the misinterpretation of sources being the biggest one. This leads them to conclude that Moravcsik's original conclusion about some of de Gaulle's policies does not hold closer scrutiny 11/
Overall, it is true that there is no good evidence about confirmation bias in qualitative research. However, my reading of the evidence that we have is: We should be concerned about bias because different pieces point to its presence. 12/
This does not mean that Veil of Ignorance process tracing is necessarily a good technique for addressing it. However, it points to the broader importance of reflecting upon potential ways to detect and diminish bias in qualitative research (maybe more on this [much] later) /end

I’ve asked Byers to clarify, but as I read this tweet, it seems that Bret Stephens included an unredacted use of the n-word in his column this week to make a point, and the column got spiked—maybe as a result?


Four times. The column used the n-word (in the context of a quote) four times. https://t.co/14vPhQZktB


For context: In 2019, a Times reporter was reprimanded for several incidents of racial insensitivity on a trip with high school students, including one in which he used the n-word in a discussion of racial slurs.

That incident became public late last month, and late last week, after 150 Times employees complained about how it had been handled, the reporter in question resigned.

In the course of all that, the Times' executive editor said that the paper does not "tolerate racist language regardless of intent.” This was the quote that Bret Stephens was pushing back against in his column. (Which, again, was deep-sixed by the paper.)
