Thank you for your question!
This is the type of thing where there really are all sorts of examples, especially nowadays with how convoluted our media ecosystem has become. A common example that is used in research is the idea that “80% of dentists recommend Colgate.” If you saw that on a label or advertisement you would be led to believe that 4 out of 5 dentists think Colgate is better than all other brands. The survey though allowed people to pick more than one option, so it doesn’t necessarily mean that it was the best choice.
