The root is that nobody asked me in a metaphorical way to take a vow either.

Er, yes, someone has. In fact, Eliezer has asked you to do so. From the Twelve Virtues:

The third virtue is lightness. Let the winds of evidence blow you about as though you are a leaf, with no direction of your own. Beware lest you fight a rearguard retreat against the evidence, grudgingly conceding each foot of ground only when forced, feeling cheated. Surrender to the truth as quickly as you can. Do this the instant you realize what you are resisting; the instant you can see from which quarter the winds of evidence are blowing against you. Be faithless to your cause and betray it to a stronger enemy. If you regard evidence as a constraint and seek to free yourself, you sell yourself into the chains of your whims. For you cannot make a true map of a city by sitting in your bedroom with your eyes shut and drawing lines upon paper according to impulse. You must walk through the city and draw lines on paper that correspond to what you see. If, seeing the city unclearly, you think that you can shift a line just a little to the right, just a little to the left, according to your caprice, this is just the same mistake.)

This is the exact same thing that the article is saying:

In order to study the art of human rationality, one must make a solemn pact with themselves. They must vow to stop trying to will reality into being a certain way; they must vow to instead listen to reality tell them how it is.
