I honestly remembered seeing something to the contrary, despite it being counterintuitive.
As for the poll, well, not much, the top line is skewed by the weighting which would assume a Lamont led government in 2016 in defiance of all other available polling data, as well as a relatively large vote for the Tories. Below that headline is the number of Labour voters defecting to Yes semes ot have an upward trend, which if continued as it has over the last year could see ~25% of them vote yes on the day. It's that upwards Labour yes support and a kick up in SNP support from the alst one that seems to drive the 3% to yes swing. Ironically, Panelbase, every Yes supporters favoured polling company, would likely show the same results as quite static, as their Holyrood weighting would mean the SNP wer epresnet in alrger numbers such that any swing to yes from labour would form a lower percentage of the overall sample.
Other than that, the gender gap is still alive and kicking, f**k knows how you deal with that. As for the white paper, it looks like amongst the undecided voters it's had a slight positive effect, but then I doubt it's intention was to provide an immediate masive swing in the polls anyway.
