There is a second half to this that has not been said yet. It helps to ask what evidence would change your mind before you look at any. If nothing would, the discussion is not about evidence, and it is better to say so early than to spend nine posts discovering it.

Moderator note: a couple of off-topic posts removed. Thread quality here is what the rules are for. Keep it up.

One thing that is still open after VanRx_Mike’s answer:

How would you tell the difference between that and the alternative explanation?

This is where I part company with the consensus forming above. The objection nobody has made: this only works if the measurement is doing what we assume it is doing, and that assumption has not been tested here.
