I never read the introduction of an article

I never read the introduction of an article, seldom the discussion section, but I always scan the methods and sometimes (if the methods warrant it) also the tables and figures. It seems that I am not alone here.

The survey indicated that individuals at different career stages valued different sections of scientific papers, and skill in reading the results section develops slowly over the course of an academic career.

So why do we still write papers with an introduction that is longer than 1 sentence?
