I think it would be fascinating as well. If one wanted to conduct a less technically sound experiment, one could simply go on various social media and make comments that have the exact same point of view but with and without qualifiers and document the responses they get.
One downstream implication could be how AI models use this data for context. IE, if something needs qualifications maybe it deems it as controversial whereas if something does not need qualifications it is not controversial.
