If you really want to do this then here would be a good place to start digging: https://github.com/rails/rails/blob/ed7614aa7de2eaeba16c9af11cf09b4fd7ed6819/activemodel/lib/active_model/validations/validates.rb#L82

However, to be honest, inside of ActiveModel is not where I'd be poking with a stick.
