The polling itself is easier as you're not predicting what "don't know" means, the interpretation of the results I would argue isn't.
Say you're being told that your policy is too expensive, and the reason for that is that people cannot see where the money is coming from or understand how the investment will pay back, unless the pollster, who then has to conduct themselves identically to their colleagues elsewhere, sits in a participants living room all day probing for hours on end, you'll still get a data set that requires a lot of analytical interpretation.
Even after that interpretation has been decided on, you then have to look at what the groups of people you are targeting are saying and assume that you are right about that strategy as well. Although it can provide far more data and deep insight than binary "will you vote for us, yes or no?" polling, it's still very much routed in approximation and characterisation.
It's pretty clear the country requires a new government, and that both main party leaders are not popular. The length of time those numbers have been available for shows consistency. I would argue that it's about time they started being a bit daring this close to a GE, stick to some policies, create larger dividing lines, and defend them vigorously. Unless of course they've not convinced themselves on some of their own policies, hence why I think this is more to do with Reeves as much as it may be with any focus groups.
You are working backwards from how polls actually work, you don’t collect the data then work out what it is you want to know and whether you asked the right people. You model the questions on what it is you want to know and model the sample population to match the people you are interested in.
If you have an agenda you can manipulate a poll to come to the answer you want (fantastic example in an episode of yes Prime Minister), but that’s a deliberate act (usually done by think tanks to push an agenda). Political parties do not want their polling distorted like that as they actually want to know what people think (hence why it’s a secret poll, they don’t want it leaking if it turns out bad for them).
As I say it’s been badly managed but I think the error was giving a number in the first place.
