One of the case studies in my M.Phil thesis was persistent organic pollutants (POPs) — a class of mostly pesticides which have been restricted under international law because they harm humans and other species, persist in the environment for long periods, and bioaccumulate in food chains, rising to higher concentrations in each level of predators.

After shutting down everywhere in Canada except Ontario and Quebec in 2018, Greyhound is now shutting down in Canada completely, aside from some routes across the border by the American company (Toronto to Buffalo and NYC; Montreal to Boston and NYC; Vancouver to Seattle). When the government is so keen to help out those who […]


In a development that illustrates the global dynamics of climate change China’s emissions now exceed those of the entire developed world put together. Since at least the 1990s the basic nature of a global deal to control climate change has been clear. States like Canada with the highest historical and per capita emissions need to […]


This week’s issue of The Economist has Taiwan on the cover and describes it as the “most dangerous place on Earth”. It is widely reported that a central purpose behind China’s military buildup and particularly the acquisition of naval and amphibious warfare capabilities is the country’s ambition to conquer its democratic neighbour.

There is an intriguing hypothesis about the rational mind: while we think of it as a weigher of evidence that contributes to the decisions we make when faced with a choice, it’s possible that its real role is to construct a story after the fact about why we made the choice we did for instinctive […]


The gradual sorting of partisans into the “correct” parties during the last fifty years has transformed a nation of cross-cutting political identities into a nation of increasingly aligned political identities. As Democrats and Republicans grow socially sorted, they have to contend not only with the natural bias that comes from being a partisan but also […]


U.S. Treasury Secretary Janet Yellen has raised the idea of a coordinated global minimum corporate tax, with the aim of disrupting ‘race to the bottom’ dynamics in taxation and the shift of assets to tax havens. Global coordination is likely a necessary prerequisite to effective wealth taxation. It could also help to improve the tolerability […]

Even in the most basic definition of a group, [social psychologist Henri] Tajfel and his colleagues found evidence of ingroup bias: a preference for or privileging of the ingroup over the outgroup. In every conceivable iteration of this experiment, people privileged the group to which they had been randomly assigned. Ingroup bias emerged even when […]
