Explanation:

Often it is tempting to look for a quick and easy explanation for a problem or to see an easy solution as the answer. When it comes to major issues of the day, in almost every case, people get the wrong answer because they oversimplify. The reason why subjects like euthanasia, abortion, and tax rates are controversial is that they are complex. If they were as simple as educators and those in the media often make them out to be, then there wouldn't be any controversy.

Examples:

(i) Those who oppose abortion are just imposing their religious beliefs on the rest of us. (Though some oppose abortion on religious grounds, it is not a religious issue, it is a human rights issue. Note that this like of reasoning is also a straw man.)

(ii) The solution to the education problem is to spend more money on the schools. (The United States already spends more per student that any other country, but still has the worst results of any industrialized country and worse even than many developing countries. This proves that simply spending money does not solve problems.)

(iii) Though difficult to describe in a short example, the presentation of the theory of evolution is inevitably presented in an oversimplified manner. For instance, many are taught that a "simple cell" is just that - simple. There is no such thing as a "simple cell." The simplest cell is almost incomprehensibly complex. This complexity is a serious problem for the theory of evolution, so it is ignored.

(iv) Almost anything that appears on a bumper sticker.
