Say you’re having trouble understanding why your brother does everything his new “friend” tells him to do. He’s never acted like that towards anyone before; your model of your brother is missing something. Fortunately, you’ve seen such behavior before, explained by a different model, the one of your co-worker. That model made you realize that, like your co-worker, your brother finds his new friend much higher status and feels lucky receiving his attention. Not only did you strengthen your brother model, you’ve also collected more evidence that such behavior is more likely status-related and less likely person-specific, making all your models more robust.
