Numerology has no lab, no control group, and no dataset of lucky versus unlucky lives to draw from. What it has instead is a century-plus of writers agreeing, largely with each other, on which numbers deserve the best press.
That agreement clusters hard around the master numbers. 11, 22, and 33 are treated as amplified versions of 2, 4, and 6, carrying extra symbolic weight in most Western systems. From there, opinions splinter, and the further down the list you go, the more the rankings depend on which book you're holding.
