I don’t think I would agree with that as a general explanation of the results.… in order for us to get the results we did, you’d need some people who were selecting meat when there two veg options to select meat-free when there are three veg options. The folks who always selected a meat-free dish (around 20% of respondents) don’t drive variation in meat-free meal selection across different menu types, and so can’t explain our results. Same applies to those who always selected meat-based dishes. Indeed the regression results on menu characteristics were identical when we excluded those respondents (see Table 10 of full-writeup).
But I think your quote above might be able to explain why the pp change in meat dishes chosen is lower than the change of menu options. Would probably make a few changes though (completeness at the expense of brevity).
“When offered more non-meat menu options (20pp increase), survey respondents selected fewer meat-based dishes (12pp decrease). Respondents, on average, selected a relatively low share of meat-based meals across the experiment. This is one reason why the fall in the share of meat-dishes is smaller than the change in the share of menu options.”
