Big ideas rather then big data, please

With many powerful academicians, lobbyists, professional societies, funding agencies, and perhaps even regulators shifting away from trials to observational data, even for licensing purposes, clinical medicine may be marching headlong to a massive suicide of its scientific evidence basis. We may experience a return to the 18th century, before the first controlled trial on scurvy. Yet, there is also a major difference compared with the 18th century: now we have more observational data, which means mostly that we can have many more misleading results.

I think the situation is even worse. Indeed, we can only grasp the nature of reality with action, not with contemplation (pace Ioannidis). But experiments (sic) as in RCT are also part of the problem: we only understand the world by testing of ideas that appear to bring coherency to the natural world. A/B testing is inadequate for this task — although it may well be all we have left.
