Amateur hour

Poll results are often a little like the Rorschach Inkblot Test – the ink blot that some psychologists show their patients. You see what you want to. That’s certainly the only way to explain how the Dominion Post has reported a poll it has done on tax cuts. The front-page story, penned by Dominion Post political editor Tracy Watkins, reads:

Alarm bells will be ringing within the Government after a new poll showing 75 per cent of New Zealanders and a staggering two out of three Labour voters want tax cuts now.

The Fairfax NZ/ACNielsen poll for The Dominion Post will shake the Government’s pre-Budget complacency that tax cuts are not an election winner, with most voters who favour an immediate cut in taxes also of the view there is room for a reduction in government spending.

The results are the clearest indication yet that National is starting to win the argument over whether there is enough money in the Government’s coffers to pay for tax cuts without cutting into core public services.

David Farrar interprets this result with glee, saying voters are chanting:

What do we want?/ Tax Cuts/ When do we want it?/ Now.

Well, no. This is a completely erroneous interpretation of the results.

Let’s recap. Two questions were asked. First: Would you support or oppose immediate tax cuts? Second: If you support tax cuts, would you still support them if public spending was reduced as well? The results for question one were 75% yes, 24% no. The results for question two were 64% yes, 35% no.

The key to interpreting these results is to realise that only those who supported tax cuts in question one were asked question two. So, here’s a question for all those sixth-formers out there: what percentage of all people polled support tax cuts if they mean cuts in public spending as well?

75%? Nope. 64%? Nope. Actually, 48%, or less than half of those polled support tax cuts if they mean cuts in public spending.

75% of the 1110 polled said they supported tax cuts. That’s about 830 people. Only these 830 people were asked if they would still support these tax cuts if they meant a cut in public spending. Of these 830 people, 64%, or about 530 people, said yes. So, out of a total of 1110 people, only about 530, or 48% of the total number polled, said they supported tax cuts if this meant cutting public spending. That’s less than half. On the other hand, about 550 people, or 50% of those polled, said either that they didn’t support tax cuts at all or that they didn’t support them if they meant cuts in public spending.

So, what does this all mean? Well, 50% of those polled support Labour’s position (that tax cuts shouldn’t be made if that would mean public spending cuts), compared to 48% who support National’s position (that tax cuts should be made, and one of the ways to pay for them is to cut wasteful public spending).

So, how on earth is this a victory for National? Why on earth will this set off alarm bells ringing in the Government? And given that only 38% of Labour voters polled said they support tax cuts even if they meant public spending cuts, how on earth can you justify the headline “We want tax cuts now: Labour voters”? Does the Dominion Post simply not understand its own polling?

If that’s the case, can I suggest the Dominion Post‘s political editor does a refresher course in sixth-form statistics? As for David Farrar: you’re a pollster, son. Shame on you.
