Intuition is not a default
All the raw materials that the brain uses to make that snap decision are provided from our environment.
My son has dark skin. When he walks down some streets, people get nervous. There is no reason for this as there is no real danger. My son is educated and respectful, yet when he walks past people women visibly tighten their purses and walk out of the way (he and I have tested this together where I will walk by with my white face and watch the differences in behavior).
Leaving aside the anecdotal character of Max's claim, the reaction based on race is not necessarily intuition. Although intuition is surely an unconscious (or other than conscious) process, it is not axiomatic that all other than conscious reactions are intuition. You're the one doing the conflation here. This is also not a fair response to my criticism, which is that you claimed that racism is caused by intuition, while subsequently acknowledging that racism is a product of indoctrination. I say you can't have it both ways.
That people may or may not use intuition wisely is not evidence that intuition is somehow an inferior process to conscious, so-called rational thought. The citation that Max provided points out that people make flawed based on conscious, "rational" thought because they don't consider all the data, or don't have all the data, or don't weigh it properly.
