It turns out Al Gore's famous frog metaphor is not quite right; as Friedrich Goltz has demonstrated, "frogs will indeed remain in slowly heated water, but only if their brain is removed.” Please adjust your expectations of global human intelligence accordingly.

Science proves metaphors are literally true.

For every congenial character who can warm a room, there’s another who can bring a draft from the north, a whiff of dead winter. And even if the thermometer doesn’t register the difference, people do: social iciness feels so cold to those on the receiving end that they will crave a hot drink, a new study has found.

The paper, appearing in the current issue of the journal Psychological Science, is the latest finding from the field of embodied cognition, in which researchers have shown that the language of metaphor can activate physical sensations, and vice versa.
