It is NOT confirmation bias, because you just got into cars, so you have nothing to confirm yet. it's Choice-suportive Bias . You bough an android, then it's far better than apple, you bough a nissan, it's now superior to cherokee, You like Jazz so it become a superior musical genre, you drink wine that's now the most fancy drink in the world, etc.. Once you made a choice, you can only listen to things that confirm that choice... yeah retroactively it sound a lot like confirmation bias. hum.
Oh man... yeah. It's like the Heisenberg Uncertainty Principle... as soon as you know it's a bias, the definition of the bias changes. If you don't know it's a bias, then that's a different kind of bias. If you want to keep your sanity, DO NOT read the wikipedia article on biases. If biases were plotted out like a Venn diagram, it'll look like a Spirograph drawing:
This one does offer a more complete picture of what is going on with people I am talking about although I wonder if confirmation bias starts to play a role as time goes by and we see people seek out information to back up that original choice. Almost like as we begin to learn more choice-supportive bias isn't enough and confirmation bias swoops in to save the day by steering the person in the direction of what they want to hear. That's an interesting one I didn't know about but it does describe how people do this in some scenarios such as the used car one cited on that wiki page. Or when somebody puts their opinion out there on social media and then when shown all the negatives sticks with the original. When that same person now goes and only seeks out people or information that supports their view I suppose that would then be confirmation bias.
