It varies quite drastically on the language being translated to/from.
You might be able to get subtitles projected in your field of vision in real time pretty soon, but we are still a fair way off perfect translation for many languages, even a way off just ok translation for many.
A quarter is half of a half
When you divide by 0.5 (or any number) you are saying how many 0.5s (or other number) can I fit in that first number. You can fit half of a 0.5 in 0.25
Yep, look up the nocebo effect. It’s exactly that.
It’s not so common being an issue like the example describes irl for medication as generally people who don’t think something will work simply don’t take it, so it becomes more a compliance issue, but certainly is a concern for eg physical treatments - patients are more likely to report pain during a procedure if they go into it expecting it to be painful. Also mentioning side effects of medication makes patients more likely to experience them.
Yes. If you give two sets of people sugar pills and tell one set they are sugar pills, and the other that they’re eg painkillers, the latter group will report (on average) a reduction in pain related issues while taking them.
This is why alternative treatments that don’t medicinally do anything, like homeopathy, can appear to be effective - people believe they work and so they do, but if they just believed a cheap sugar pill they would help them, it would do for much cheaper. Even better get real meds that you believe in, and you get actual medicinal effect with a placebo boost.
Good Pharmaceutical trials are generally “blind” for this reason, ie there will be a control group getting a placebo to compare the effect of the medicine to that, rather than to nothing as comparing to nothing would make most things appear effective. Even better is “double blind” where the researcher doesn’t know until after either, so that their interactions or behaviour don’t give anything away, and that they don’t bias their analysis.

We should get rid of C. It adds nothing to our language but konfusion whitsh we kould easily kope without, and spelling Pasifik Osheon kould bekome simple.
Edit: after reading that sentence I take it all back.
