It's certainly related. Cached Thoughts have always suggested repeating a meme, to me, which is different than supplying a ready-made answer. For example: Cached Thoughts rely on the conclusion coming from outside of your mind, and merely accepted as truth without any analysis. Canned Answers can be your own conclusions from earlier, thoughtlessly applied to a situation they might not be relevant to, or just used as an escape so new thought doesn't have to be done.

But yeah, quite similar. Good to know I originally came up with someone found here. Go ego boost. ^_^
