Out of the 26 polls since the GE, 13 are pro indy 13 aren’t. But it’s worth noting that 9 of the 13 pro-indy polls were commissioned by strongly pro-Indy groups (The National, The Herald, STV News), which seems like it could have some selection bias.
The Herald[1] and STV News (neutral as a broadcaster) are not strong Pro-Indy groups.
The National certainly is.
