Break In Question?

Of course the brain can be fooled. Doesnt mean that it always is and you must take into account the difference between consequential and inconsequential stimuli. Chosen exposure versus forced. A consistent irritating loud noise is not processed the same as a pleasurable aria.  

Oh and polkalover nobody cares what you think because, well, you love polka. Is your wife too fat or just right? If you are still together you neednt answer.

In psychology, "outside bias" generally refers to outgroup bias (favoring your own group) or the actor-observer bias (blaming outside or situational factors for your own behavior while blaming others' personalities). Tribalism.

When a company or a friend suggest that your stereo will be greatly improved and that the sound difference will be CLEARLY audible. That's your 'belief group mentality' creating a bias in your weak, susceptable human brain.

Hope that helps.

Apparently the term has no single agreed-upon meaning.

A suggestion may create a bias. Or it may not. If you believe otherwise, that's a bias.

Ahhh yes, the classic ad hominem argument, the laziest of all logical fallacies. Have a nice day!
