The paradox of choice is that the more options we are given for a particular choice, the less likely we are able to make a choice. Penelope Trunk discussed it in her article about taking a job, any job  and references Dan Ariely, an MIT behavioral economist, and his book Predictably Irrational. In the book, Ariely discusses a study about how people ended up buying more jam when given six potential samples versus twenty four. Twenty four potential samples was simply too much and people ended up not deciding, even though they had more information.
How does this apply to banks and credit cards? Too much information paralyzes us. It paralyzes me. In the case of jams, there’s no pain in not buying a particular flavor. In the case of credit card debt, there’s a significant pain in not paying down a card. With a bank, there’s a bit of pain in interest not earned and a bit more if you overdraft because you forgot which account held how much (or you forget how much you need to keep in an account to avoid fees because you have too many accounts ). Too much information, like juggling many balls, hampers our ability to make good decisions and causes us unnecessary pain.
The solution is the simplify your finances .
If you have credit card debt, pay down the smallest amounts first. This may sound similar to Dave Ramsey’s Snowball technique and that’s because it is. However, rather than focusing on the psychological benefits (yay! another debt conquered! let’s get the next one!), I argue that removing one headache from your life, even if it’s not the most financially distracting one, is beneficial. Next, try to consolidate bigger debts into as few accounts as possible without sacrificing the interest rate. By not sacrificing the interest rate, I mean don’t consolidate lower interest cards to higher interest cards (which sounds obvious but sometimes we make mistakes). The number of credit cards offer zero fee 0% balance transfers are dwindling but they often have a fee transfer cap that could be to your benefit.
With banks, don’t keep accounts you no longer need. I kept an old employer’s credit union account open for a year and a half and it cost me $20. I had transferred money into that account from my Emigrant Direct account and written a check. The check didn’t get cashed for several weeks and before it could be cashed, I went into my account and saw some money sitting around. Not remembering why the funds were there earning a low interest rate, I transferred them back and got dinged with an NSF. While I was able to get the NSF removed, it was entirely my mistake but caused by keeping an account I didn’t need or use anymore. There are no negative credit impacts of closing bank accounts, so close the ones you don’t need anymore and drop juggling that ball.
Simplify your life and reduce the number of things your brain has to manage, you’ll be happier and richer for it.
On a happier note, my post on the Top 5 Online Banks  made it into this week’s Carnival of Personal Finance hosted by Canadian Dream .
