Hey its is more 'fun' than that. (AKA even more cyclical)
Consider 3 educational institutions, it is entirely plausible (has been observed to occur)
That 'A' is using program 'a', B is using program 'b' and C is using program 'c'
all of these are >>accurately<< observed to be ... failing
They all swap to new 'better' programs...
A is now using program 'b', B is now using program 'c' and C is using program 'a'
and all are again >>accurately<< observed to now be much better than before.
Education is an interpersonal process (not bucket chemistry). How a new and exciting the program is (feels) for the humans implementing the program has substantial effect on how well the program works. And it might be tempting to want to "fix" that but the people implementing the programs are indeed people, and how enthusiastic they are, is TBMK the actual most important factor in how well the programs work.
If they continue to cycle through programs a,b,c for all eternity and it continues to produce "improvements" (followed by inevitable decay/boredom) then there isn't actually a problem with that.
