>Interestingly enough liberals are more likely to know about QAnon than conservatives

probably because the kind of people who discusss QAnon as a phenomenon are more likely to be young, actively engaged in (digital) politics and possibly more educated, which correlates with political leaning, in particuar in the last election. As Pew points out, NYT readers or NPR listeners are also much more likely to have heard of it.

I wouldn't be surprised if liberals score higher if you question US demographics about pretty much any internet phenomenon just because of the make up of the group.
