I've always thought that it did add a slight honey taste to the beer, but I really wonder how much of that is psychological. I've done enough study of how preconceptions effect perception to be skeptical of my own tastings when it isn't done blind. And I haven't done that with honey malt.

I was an English major in college, and that's one I still get wrong almost every time!
I usually ask myself, if I change the word to "create" or "change", which one makes more sense? Are you creating perception or changing perception? Change is affect, create is effect.
It might not work in all sentences, but it's easy to remember which is which - affect has a C in it, and change starts with C.
