Keeping up with the Jones is common human behavior. Doing what seems easiest is common human behavior.
To me, if someone truly wants to change, they should start by forcing themselves to think about financial efficiency instead of feelings. And that's especially true when you are in a debt emergency.
I get the the debt snowball, Ramsey-style, works for some people, and maybe it even works for some people who would have given up if they started with a larger debt and that just took too long. But somehow, I think people who cave because they don't have a warm fuzzy feel good moment where they can cross something off a list probably haven't learned enough or changed enough to stay out of debt for very long anyway. They are still prioritizing what feels good over what makes financial sense, and I don't see how that's much difference than getting a Starbuck's latte and driving a Mercedes instead of making your own coffee and driving a 14 year old For Focus (or riding a bike).
This isn't just feel good stuff. It's about doing what works, not just for some people, but for more people than any other method.

The satisfaction of paying of a debt is real, and that satisfaction is what teaches you a new habit. It's a very real reward, and your brain seeks reward. The
anticipation you get from seeing a debt approach zero is one of the most rewarding things that happens to your brain. Here's another example of why anticipation is important:

Too many balls in the air and you start dropping them. Pound down one debt, then another, then another.
You may think its a trick or cop out, but really its just taking advantage of the tools available in our built-in reward mechanism.
Also, the fact is, that once people get on a roll with this and get serious about paying it down, the math doesn't even make that much difference. Having a higher interest debt hang around a bit longer doesn't really make a difference in your life, compared to the development of new habits of finance.
