When I see some product advertised as "made with science" I usually assume they have done zero actual research, no studies whatsoever and its just meaningless marketing trash. Those are products I generally avoid
So to summarize and (over)simplify: people want science to do things for them, but they don't actually like science. As a science-lover working in STEM, this is sad to hear, but not at all surprising.
one major issue is that calling out sciences signals or reminds the person that the product is mass produced in giant industrial facilities. Without mentioning science that isn’t always realized for a random person.
You're right, it's definitely an issue that people are more likely to turn down the same product if they think it was made in a big building owned by a group of people instead of, say, in an old lady's home.
