This is spot on. I didn't care about my credit score for a long time...until I did. An autopay error from one bank account to another resulted in a late payment and a 50 point drop. Coincidentally, I also needed to rent an apartment and apply for a small car loan.

Both of these things were made much more difficult, even with just a 50 point ding. The score recovered quickly and I learned my lesson. It was somewhat eye opening for me. One thing I do wish: after tons of research and discussion with "experts" it seems pretty difficult for the average American to predict a rise in their credit score once it takes a hit.

Sure, paying bills on time and carrying low or no balances help, but at the same time, paying off a loan can either help or hurt you, being added as an authorized user to a partner's card can be beneficial or not even acknowledged. I wish the algorithm for determining this was a bit more transparent, i.e. What are the mechanisms at work behind that credit report? Not some vague "your score may have fallen because of..." Or "doing this might help your credit..." I feel like the lack of transparency makes people fear credit to a degree.

I suppose the information is hidden to prevent gaming the system. As someone mentioned in another thread, they took out a loan for $1000, sat on it and just paid it off. Credit score goes up with zero risk for just the cost of interest. If the algorithm were exposed, it would be easier to game.

If the things they were tracking are reliable indicators of "credit-worthiness" then it would not matter if you "game the system" or not.

It's like that story about robbing the bank. First, we get jobs at the bank. Then we go in and work the jobs every day... (spoiler: we never actually rob the bank, because we get cushy jobs with benefits, and retirement plans. That's brilliant!)

Anyone with a good credit score can decide to burn their credit at any time. Loss prevention can also step in and cancel your cards at any time if they decide that you've gone off the deep end. They probably won't... but they could.

Any metric is gameable. And, if the current algorithm is the best way to predict "credit-worthiness," publicizing its details will drive consumers toward different behavior, which makes it less powerful

Imagine Google made its own credit score, based on your searches, social contacts, etc. It turns out that someone clicking on ads for product X have a very high likelihood of repaying their debt. This information ends up publicly leaked.

What do people start doing? How does this affect the quality of Google's credit algorithm?

Not any metric is gameable.

A reliable indicator of whether you will pay your bills in the future might be whether you paid your bills in the past. There is no way to game this metric, other than by paying your bills.

You just chose a metric that would be easily gamed and said that any metric is gameable.

Except the exact situation outlined above, in which a person generated bills that they otherwise wouldn't have needed, for the sole sake of having more bills "paid on time".

[yebyen]

So, how does one get over in gaming this metric? Take out a lot of credit accounts once your credit is good and then default on them? What's the end game where they come out ahead? See prior comment about the bank job... that's just called having and ruining your credit.

[SilasX]

That's overstating it. "Whether you've paid back all debts on time" isn't gameable.

[jacquesm]

Actually it is. Simply take out a couple of loans you don't need and pay them off at the agreed upon schedule.

[ProblemFactory]

Taking out loans that you don't need, not spending the money, and paying them back on time (with interest) should be a very positive credit score indicator.

It shows that the person is planning ahead, is careful with not overspending even if they have cash available, is organized enough to make all the monthly payments on time. To me that seems like a better signal than someone who does need the loan.

How would a person who takes out the same loan, but actually spends the money be a better credit risk?

[SilasX]

That doesn't change the value of "has paid back all debts owed?".

[tome]

But that is an indicator of credit worthiness. Having the financial discipline to spend your money repaying your obligations rather than treating yourself is a worthwhile indicator, regardless of how the situation comes about.
