Most of the “data” that we have on double crux is of the informal type, from lots of experience doing double crux, trying to teach people double crux, facilitating double cruxes, watching people try to double crux, etc. But some of the data consists of numbers in a spreadsheet. Here are those numbers.
At workshops, when we teach double crux we have people pair off, find a topic which they and their partner disagree about, and try to double crux. We typically give them about 20 minutes, and have a few staff members floating around available to help. At the end of the class, participants get a handout with three questions:
How easy was it for you and your partner to find an interesting disagreement to apply the technique to? (0 = very hard, 10 = very easy)
Was your conversation valuable / productive / something that you learned from? (0 = not at all, 10 = very much)
Did you and your partner find a double crux? (No, Sort Of, Almost, Yes)
With a sample of 124 people, the averages on these were:
6.96 Easy to find an interesting disagreement
7.82 Conversation was valuable
49% Yes found a double crux
The value of the conversation rating was 8.08 among those who found a double crux (“Yes”, n=61), 8.14 among those who easily found a disagreement (rating of 7 or higher, n=86), and 8.35 among those who both easily found a disagreement and found a double crux (n=43). (In contrast with 7.56 among those who didn’t find a double crux (n=63) and 7.08 among those who had difficulty finding a disagreement (n=38).)
Thanks for presenting this helpful data. If you’ll forgive the (somewhat off topic) question, I understand both that you are responsible for evaluation of CFAR, and that you are working on a new evaluation. I’d be eager to know what this is likely to comprise, especially (see various comments) what evidence (if any) is expected to be released ‘for public consumption’?
