A humble little subject, but I just thought I'd put up a resource piece about how often federal Newspolls are released and have been released over time. The timing of federal Newspolls is frequently a subject of discussion, much of it clueless or biased. One fairly prominent claim links the switch to federal Newspolls in the early 1990s with the frequent turnover of major party leaders, although there is actually no evidence that this is true at all. On social media, Newspolls are eagerly awaited and considered "due" every second Sunday, mostly by one-eyed Labor supporters. If Newspoll fails to appear this is claimed to be evidence that it is being "hidden" because the results are bad for the Coalition. If this were actually the case, Newspoll would skew towards the Coalition compared to other polls (it doesn't), Newspoll would have gone AWOL during obvious Coalition low points like the Hockey budget, the Prince Philip knighthood and even the collapse of Malcolm Turnbull's "utegate" attack on Kevin Rudd (it didn't), and Newspoll conspiracy cranks would be able to post reliable advance predictions of when Newspoll would come out (they don't.) But those tweeting these nonsense never let the facts get in the way of their inane barracking.
This week I saw a new strain of the viral dumbness that is Newspoll truthism - a claim that Newspoll was becoming less frequent in order to string out the time it would take for the Coalition to lose 30 consecutive Newspolls on Malcolm Turnbull's watch. (Turnbull has lost 14 in nine months, while Abbott's 30 spanned sixteen months, making Newspolls 17% more widely spaced so far during Turnbull's losing streak.)
