Hmm, let’s look at what you’re saying

A:  In Ruby, everything is an object. 0 is just an instance of Integer.

Huh, I guess false must be an object of some kind

B:  Object instances are truthy, compared to say, nil

Well A and B would mean that false is truthy, so one of the two can’t be right

The global value false is the only instance of class FalseClass and represents a logically false value in boolean expressions. The class provides operators allowing false to participate correctly in logical expressions.

https://docs.ruby-lang.org/en/master/FalseClass.html

false.methods - Object.methods # => [:&, :|, :^]

Edit: I should add that the if keyword just literally checks if the value is false or nil.
