The "-logy" comes from Greek which means science: https://en.wikipedia.org/wiki/-logy and https://en.wiktionary.org/wiki/-%CE%BB%CE%BF%CE%B3%CE%AF%CE%...

What about Scientology which has both science and ology? Is it science science?

I think that's like a double negative. Which would imply that Scientology actually IS science, which is ridiculous of course. I think "science" in the title only means "not science" when conveyed in the language you're currently using.

A common misconception! It's actually the science of the color cyan, but people kept mispronouncing "Cyantology". ;)

isn't neurology more to do with the physiological aspect? Neuroscience is a bit more like behavioural psychology.

neuroscience is physiological, but it deals with the study of neurons and neuronal systems rather than the output of behaviors. I always thought neurology was more of a medical field application of neuroscience.

Is that really an argument in favor of it being a science? Isn't behavioral psych going through a "replication crisis"?

No. It’s saying that GP has completely miscategorised notwithstanding your clumsy strawman.

What "strawman"? You introduced behavioral psych to the discussion. You seem more certain now, however...

behavioral psychology is NOT neuroscience behavioral neuroscience is different than behavioral psychology
