One of the things we hear all the time from death penalty abolitionists is that support for capital punishment is declining (which is true, slightly, over the last decade). Heard a good deal less often is how much the support actually is. Hint: It's been at or above 60% for forty years. (It was below that level for about the twenty years before that, or from roughly 1954 to 1974).
To illustrate how misleadingly support for the death penalty gets portrayed in the media, here's a little quiz:
Do more people think (1) the death penalty is imposed too often, or (2) the sun revolves around the earth?
Congratulations! Right again! More people think the sun goes around the earth than that the death penalty is imposed too often (scroll down two-thirds of the page to find the graph).
P.S. I suspect these two groups largely overlap.
