I don’t really believe you could do such a thing empirically. I mean it just depends on scale as you indicated. I have never been a fan of ‘social’ sciences either.

Just like Christensen’s Dilemma books are mostly just anecdotes combined with patterns in history. As many such business books are.

But in my short time on this planet I’ve seen it in countless forms where I strongly believe it deserves such a title as “iron law”.
