David Cameron

A politician wants to vote for the decriminalisation of marijuana. But she knows that opinion polls suggest that her electorate is against easing access to weed. Although she cares about the issue, she also cares about being re-elected. What should she do?

Should she: 1) Heed the pollsters and vote against decriminalisation; 2) Appeal to her electorate, citing evidence and appealing to their values; or 3) Just vote for it, since her electorate will support her anyway?

I think most political advisers would suggest the first or the second option. But a fascinating new experiment by David E. Broockman and Daniel M. Butler suggests politicians have broad latitude to shape public opinion without any electoral cost. The third option – vote for decriminalisation – may be more viable than it appears. The research implies that politicians could worry less about what the public thinks. Read more

In his conference speech, David Cameron said a Conservative government released from coalition would make two changes to income tax by 2020. He presented the first – a rise in the amount of money people earn before they pay income tax to £12,500 – as a tax cut for minimum wage workers. He presented the second – a rise in the level at which workers start paying the 40p rate of income tax to £50,000 – as a tax cut for the middle class. Neither change is quite what Mr Cameron says it is.

The chart below suggests how much people making various incomes stand to benefit from the changes. (Source: Ben Richards.) Treat it as illustrative: the exact numbers will depend, among other things, on when the cuts are introduced. But it shows how the bulk of the benefits would be skewed towards those in the top quarter of earners.

Another thing one hears from Scottish opinion poll watchers is that there may be a version of the Shy Tory effect happening ahead of the independence referendum. This is another reason they give for why the Yes vote may lower than polls suggest.

Behind these results lies a theory: the “spiral of silence”. This is where an individual is reluctant to give his opinion because of what he perceives to be the views of a vocal majority, and where this reticence has a knock-on effect on others’ silence. (Hence the spiral.)

One paper on the subject lists three criteria for the spiral: (1) The issue must have a moral component to it; (2) There is a time factor or dynamic aspect of public opinion; (3) There is ubiquitous and consonant mass media coverage

David Cameron, prime minister, has described his government’s “welfare” reforms as a “moral mission”. I support much of what the coalition is trying to do; for example, the effective marginal tax rate for people such as Natalie should come down under Universal Credit. (It could also have come down without a massive project but that is for another post.) Any government taking power in 2010 would have had to cut the social security budget.

But the government’s haughty self-righteousness is risible in the face of evidence of unnecessary suffering. The rhetoric around benefits and the millions who receive them is already toxic. We could do without the idea that pointing out problems is somehow treacherous. If you look at what the Christian leaders are saying, as this atheist has, they are careful to focus on the practical consequences of specific decisions. There was only one side talking the language of crusade last week and it was not the ones whose job it is to promote the idea of ascension. Read more

One of the many popular myths about immigration is that politicians ignore the issue. On the contrary, they cannot talk enough about how they Share Your Concerns. In this morning’s FT, David Cameron Shares His Concern in a 1000 word op-ed. It has been met with the predictable fiery reactions from all sides of the debate. Read more

David Cameron announced the figures in the Sun, which shows a picture of him next to a snap of Margaret Thatcher promoting her Right to Buy scheme. It should not take too long to figure out the prime minister’s preferred interpretation of the first figures relating to the mortgage guarantee scheme: the only bubble Help to Buy is inflating is one of happiness in the hearts of ordinary people. Read more

“Illegal, yet legitimate”, was the Independent International Commission on Kosovo’s verdict concerning Nato’s military intervention in 1999 against the Serbian government. As the US, UK and others discuss action against Syria, the war in Iraq inevitably looms large. However, it is the case of Kosovo that is being studied by lawyers inside the Obama administration (according to the New York Times) and debated on legal blogs. Read more
