But is that because of their past experience i.e. buying premium eggs vs cheap eggs before trained them into a bias?

It's the same as the claims that no one knows they are sick for weeks before symptoms. If you're unhealthy and living with that, yeah, I guess you might not notice feeling off
Weeks? Regular colds and flu have incubation periods of just a few days. Diseases with incubation periods measured in weeks tend to be the more serious ones that don't occur often enough (thankfully) to be used as a good comparison point.
