Survey research offers an important mirror on society.

Occasionally, opinion polls can conjured into existence — to suit partisan leanings. This article looks at a recent example with a supposed survey of Scottish adults.

Ex nihilo

New Scottish poll has Labour overtaking the Tories…
Lab +2
Con -3…
Tories would be wiped out in Scotland…

There are multiple avenues of suspicion: no company has been named,the central estimates are missing (what share did they change to?), and the fieldwork dates are unknown.

Importantly, neither the position nor change of the Scottish National Party has been stated.

How to check

Looking at Scottish poll results: we see no survey results in July 2019.

Another aggregation of Scottish polling results is done by What Scotland Thinks. Again, no Westminster vote intention poll in July 2019 has been recorded.

There are numerous polling aggregation accounts on Twitter, such as Britain Elects, Election Maps UK and Complete Politics. None of these accounts reported a new Scottish Westminster vote intention poll.

The latest poll was conducted by Panelbase, on behalf of The Sunday Times, on 18–20th June 2019. (Image: What Scotland Thinks)

We can also go to the research company’s websites. Neither Panelbase, Survation nor YouGov are reporting any new polls of Scottish adults.

A Response

Lab 19… Con 16…
The co editor of PB reported in it last night..

‘PB’ means Political Betting, and neither their website nor Mike Smithson’s account claimed there was any such poll.

Moreover, these claimed central estimates allow us to disprove the existence of this ‘poll’. We can work the changes (CON -2, LAB +3) backwards, giving us a supposed poll of Scottish adults with:
CON 19
LAB 17

No such poll exists.

There were no Westminster vote intention polls of Scottish adults in July 2019. Fabricating polling results for partisan reasons should be excoriated.
