That was exactly my first thought. We could definitely throw the SSRI efficacy into doubt though by sampling CS fluid or something for actual serotonin content in cohorts who are subjectively feeling improved by SSRIs.

It would also explain why SSRIs take time to work - as I understand it the SSRI action is immediate and yet it takes weeks for people to notice the effects.

SSRIs aren’t the only medication that requires weeks to work.

SSRI efficacy is already in doubt, as roughly 80% of the beneficial effects are replicated by placebos; some research has suggested that the remaining difference is due to the side effects, which make SSRIs active placebos and mess with study blinding.

And, even if they are better than just an active placebo, the mechanism is probably not the effects on serotonin levels. (Discussed previously here: https://news.ycombinator.com/item?id=32160703)

That would only throw into doubt SSRI efficacy for increasing serotonin levels. Not SSRI efficacy for treating depression.
