Subject [for QI] "For every expert there is an equal and opposite witness"

Curious about the origin of this phrase. I can't find it in QI archives.

"For every expert there is an equal and opposite witness"

Quite often used to refer to expert witnesses in a trial.

Wikipedia calls it Gibson's Law, without identifying who is Gibson.

https://en.wikipedia.org/wiki/Gibson%27s_law

Frequently attributed to Arthur C. Clarke, sometimes called his fourth law.

Lately attributed to author Jasper Fforde, who appears to have used it in
a 2011 novel, far too late to be its origin.

Here's an attribution to Michel (1981), but it's not clear on this limited preview who that is.
