Repugnance is hard to predict

Widespread repugnance, or its absence, is hard to predict.  Why do the U.S. and western Europe have almost opposite positions on the legality of surrogacy and prostitution for example? 

Here's a paper that carefully looked for, and failed to find evidence of a repugnance reaction from consumers about a scandal involving a company spokesperson (but unrelated to the company's business).

The Role of Repugnance in Markets: How the Jared Fogle Scandal Affected Patronage of Subway  by John Cawley, Julia Eddelbuettel, Scott Cunningham, Matthew D. Eisenberg, Alan D. Mathios & Rosemary J. Avery NBER WORKING PAPER 31782 DOI 10.3386/w31782  October 2023

Economics has long studied how consumers respond to the disclosure of information about firms. We study a case in which the disclosed information is unrelated to the product or firm leadership, but which could still potentially affect consumer patronage through the mechanism of repugnance, as described in Roth (2007). The information in this case concerns the arrest of Jared Fogle, the advertising pitchman for the Subway sandwich franchise, who was arrested in 2015 on charges of sex with a minor and child pornography. We study how the disclosure of this information, which was widely covered in the media, affected patronage of Subway. We estimate synthetic control models using data from a large nationwide survey of consumers regarding the restaurants they patronize. Despite the close and long-standing association of Jared Fogle with Subway, and heavy publicity of his crimes, we consistently fail to detect any effect of the Jared Fogle scandal on the probability of visiting a Subway restaurant. These results contrast with past studies of negative information disclosure, which tend to find negative impacts on sales, revenue, or stock price of the relevant companies. The absence of an effect in this case suggests that repugnance did not drive demand, and that consumers largely separated the offenses of a symbol of the firm from the products of the firm.
