After you have the engine running, the marginal cost of an A/B is probably smaller than a focus group test. So if you really believe in focus groups for the results and you are also ambitious enough - probably this means go for A/B.

Disclaimer: just thinking, not knowing the costs

Definitely agree, though I think the point of this thread is we don’t know the “true cost” of A/B testing in terms of long-term lost user engagement.

Have we done an A/B test for A/B testing where we test A/B testing…
