If a gaggle of geese is called geese, then why aren't a group of moose called meese? Surely that is something someone got wrong when naming animals?

The other day a friends asked me if I had ever seen a ghost and I replied “No I haven’t” but then it made me think a bit because I really think I have. Somewhere last year I stayed at Paige’s house and she suffered from night terrors, but she couldn’t wake up from them and I was sleeping at the other end of her bed when she booted me hard in the back so I kicked her back and realized she was having a night terror so I turned around to comfort her but as I turned around I saw a short woman leaning over her going “shhhhh, shhhhh” stroking Paige’s hair and Paige actually clamed down in like 20 seconds flat. I just thought “oh she’s got it covered” and went back to sleep not really thinking much about it. The next morning I said to Paige’s ma “You sorted her out quick” and she was like “what are you talking about? I didn’t even know she had a night terror”
I was a bit shocked because no one had come into the room that night BECAUSE THE DOOR WAS LOCKED! but I know there was someone there.

just curious, but i've heard that zebra is also from the horse family. if thats true, then why don't people ride on zebras like they ride on horses? in certain parts of the world, people ride donkeys and mules too but how come no one would ride a zebra even though zebra has very similar body structure to horses?

Traditionally, quantum calculations were structured in terms of statistical probability, ie. the notion of subatomic processes being indeterministic. Some people such as Einstein and Hooft have proposed or believed in the idea of "hidden variables", ie. the idea that if we believe quantum processes are indeterministic, we must have forgotten to take something into account. They believe that a future theory, or observations, will one day demonstrate determinism.

My questions are
A) What is the latest scientific consensus on this?
B) If most scientists believe in quantum indeterminism (or aren't sure), how are philosophers such as Daniel Dennett (for example, in "Freedom Evolves") arguing against free will? What rational cases are being made for saying that free will is an illusion?

I'm guessing a case can be made, but if quantum indeterminism is still generally accepted, I don't see how such cases could be rooted in empirical evidence.

Please cite sources if possible. Thanks.
