We have not conducted thorough scientific investigation of our lamps, food or furniture. Just as one might have reasonable confidence in a proposition like “tired people are sometimes grumpy” without running an RCT, one can I think be reasonably confident that e.g. vegetarians will be upset if there’s no vegetarian food, or that people will be more likely to clump in small groups if the chairs are arranged in small groups.
I agree the lighting recommendations are quite specific. I have done lots of testing (relative to e.g. the average American) of different types of lamps, with different types of bulbs in different rooms, and have informally gathered data about people’s preferences. I have not done this formally, since I don’t think that would be worth the time, but in my informal experience, the bulb preferences of the subset of people who report any strong lighting preferences at all tend to correlate strongly with that bulb’s CRI. Currently incandescents have the highest CRI of commonly-available bulbs, so I generally recommend those. My other suggestions were developed via a similar process.
