Is marriage just mutual public rickrolling?

A researcher should offer a sufficient compensation package to get enough volunteers after explaining the risks. They should get independent medical advice too.

They can still randomize within the volunteers with treatment / placebo, and maybe use quotas, but they'd just have to extend their trial period until they'd achieved a measurably representative treatment and control group and enough volunteers to test the hypothesis to the required level.

This type of non-random sampling may very well have to be done anyway, for example if they needed the power to test efficacy and safety in all the potential dug interactions or co-morbidity scenarios. Not to mention any diagnosis requirement will also screen the sample which could be influenced by health care system resources and policies, not necessarily pure morbidity. So I think they can deal with non-random sampling in med research perfectly well.

Not if they've pre-tested on non-volunteers though.

Over my dead body!

Presumptuous, smug, know it all, clickbait titles still didn't die?

Fuck me, if I were in America and had to read toss like that, I'd probably think the population of 'scientific' americans contains a larger than normal proportion of cunts.

And a pack of condoms ?

Bike is sofa and they have ride-thru fridges.

Agreed, It'd be interesting to see the cost breakdowns.

I guess you have to spend more on tracks to get higher speeds, but still to get to 600kph you must put a lot of electricity into that thing.

If sort of feels like maglev should be able recover a decent amount of electricity during braking, but maybe there are practical constraints - or just too much loss to wind resistance.

Maybe it comes down to just a handful of magnets round a few axles being cheaper than a long line of magnets the length of the track.
