If we take the odds ratio for each individual respondent (instead of the aggregate), the median odds ratio is 10.1 -> 3.3 more bits of evidence for life in the universe, compared to somewhere in the galaxy. 25th percentile odds ratio: 2.7 -> 1.4 more bits; 75th percentile odds ratio: 75.7 -> 6.2 more bits. (This is all using the publicly available data set; looking at the aggregate in that data set I'm getting an odds ratio of 3.6 -> 1.8 more bits.)

People who believe in God/religion/the supernatural tend to give a lower odds ratio, but other than that the odds ratio doesn't seem to be associated with any of the other variables on the survey.
