Have you heard of Thalidomide?

I'm not a repugnikken nor am I a climate-change denier.

That you think I might fit one or both types, demonstrates an attachment to an unreal, idealised and ignorant view of science. Very telling.

Waving the word science at me is going to cut it, mate. I'll decide for myself what is scientific or not. I know how to do that and you, don't.

Do you actually know what I am talking about with alpha and beta, in the context of hypothesis testing? Mostly known as 'testing', of which this stuff is a report.

Have _you_ found out what the values of alpha and beta were for these reported results? I'll bet they weren't reported.

Have you read the article by Ackoff, posted here several times by me and easy to find? which is in part about alpha and beta.

Have you read Karl Popper and Thomas Kuhn? Have you taught them to students? I have. You?

If not, pull your head in and go do the reading and learning.

--------------------------------------------------------
Does the majority of your listening to music consist in going to live sighted concerts - or - like the vast majority of us, to many audio-only recordings? Which is true for you?!

And, I bet you haven't ever tried to limit any of your listening to 6 second samples.

---------------------------------------------------------
For a very long period people believed that large numbers of students in a class - the 'class size' issue - did not seriously affect learning outcomes. Because almost all studies didn't show any problem.

Much later in the 1990s meta-analysis was used to show that large class sizes did negatively affect outcomes. And that class sizes need to be reduced / that more teachers were needed.

Meta analysis had the effect of vastly increasing n - the number of trials - for one huge multi-generational study cum hypothesis test with very low values for alpha and beta.

And showed that what any halfwit could figure out was likely to be the case :- a flat out busy and stressed teacher isn't going to do a very good job :- actually was the case.

Yet, according to your standards all those hundreds, perhaps thousands of reported results - before the meta analyses were reported - were 'science'?

Because they were published in a peer-reviewed journal?

Spare me.
