Are people who are influenced by advertising “low information consumers”?

In a sense. I could give many examples across different industries, but being in China, VPNs are a subject that comes to mind. As far as advertising goes, Nord VPN is extremely well known given they pay almost every major YouTuber to shill for them. The reality is, it's a sh**tty, terrible VPN. The actually good ones are spending their money on better servers as opposed to heavy advertising. In many other fields, you find some companies charging premium prices because they've successfully marketed themselves as a high end product when truthfully they are on the lower end of the scale. Beats headphones come to mind.

If you want to make good decisions, either in consumption, politics, life decisions - anything really - you should be guided by data, rather than what others are doing, or your immediate feeling (which is manipulated heavily by advertisements). Most people cannot really do this.
