British government, still shit after 250 odd years.

Yous use ewes' yews.

To the tune of Disney Beaty and Beast

Trick as old as time,
Error all too clear,
Measure each group twice,
Claiming truth from lies,

Hello from UK. MSc in Applied Stats, no PhD, 27 years at University of Aberdeen, no barrier to progression career-wise. Caveat, all my stats colleagues have PhDs except immediate post-grads. Perhaps they keep me around as a novelty. Happy to bore you with tales from journey without PhD.

Hard for like for sending me back to the 80s playing Space Invaders 2 at Inverness La Scala cinema at 10p a go. Shit, I am getting old.

My tuppence: Not only is it allowable, it is desirable when appropriate. But I'd replace negative with challenge, acknowledge, and discount anything not useful (respectfully) when required. Otherwise our PPI colleagues are infallible.

I think some of the items included in some trustworthiness tools must also be criticised. e.g. declaring a trial problematic if they failed to meet the target sample size, or declaring a study problematic if it was placebo-controlled but used sealed envelopes (?)

Where: θ(t) = angular displacement at time 𝑡
