What’s a preconceived notion? A bias? A prejudice?
You think it runs with the individual only? Hooey!
You can create the perception, desires and wants. Edward Bernays demonstrated this over and over since selling war bonds in WW1.
I think your conflating bias with propaganda. Bias helps with it but not the only requirement for propaganda.
