Yes, the religiosity dimension has secular at one end and religious at the other. You want to establish whether that dimension is aligned with friendliness to animals. How religious people are is measured all the time, but of course methods can be questioned. I agree that would be interesting; surely a religion’s views on animals would have some affect on its adherents.
Should be fine for a microbiologist though.
You’d want to show a significant negative correlation between religiosity and friendliness toward animals. ‘Secular’ would just be one end of the religiosity dimension.
No, the logic doesn’t hold. There being shelters run by religious people does not say anything about whether they are more or less caring for animals than normal.
Self-reported religiosity and affection for animals would be a start.
The question isn’t whether they are not animal friendly, but whether they are less animal friendly. There may be a ton of them but if there are six tons of non-religious shelters, there’s a difference.
