The complexity of credit scores The complexity of credit scores

Credit Karma distills many datapoints of your financial life into a single score.

But not only is the calculation confusing to truly understand, it's a boring enough subject that many people struggle to find an incentive to try.

That is, until a major borrowing event—like getting a mortgage.

According to a poll, 44% of Gen Z'ers (1997 → 2012) don't know their credit score, with 25% admitting that they didn't know how to find out.

This screams one thing to me: a huge cohort of untapped potential users (18-25 year olds).

Credit Karma claims to have more than 100 million users worldwide, but are they providing suitable education to convert that additional cohort?

In short; no, they're not—here's why.

UX key takeaways

1. Pull to refresh

One reason why UX is a constantly evolving practice, is that popular products create new habits, which—with a little help from the ⌛️ Recency Bias—becomes expected from other services.

One recent example of this is the 'swipe up' mechanism for browsing content on TikTok. YouTube Shorts, Instagram and many others have since lent into this habit.

TikTok has been so popular that swiping horizontally to go between videos would now feel uncomfortable.

Now consider apps that have 'scores', like the two examples below. Instinctively, how would you refresh these scores?

It's very likely that you’d pull down the screen. This is usually how you'd refresh an app or website.

Here's the problem: the Credit Karma score, which you’re encouraged to take actions to modify (i.e., improve), isn’t updated in real-time—it updates every 7 days. 

Pulling down would technically do nothing.

But, UX often fights in the realm of perception, not technical limitations.

It doesn’t matter that the user can’t actually update the score immediately, they’ll try anyway.

Figma is a great example of what to do: it auto saves—there’s no reason to manually save the file. And so from a factual perspective, there’s no reason to have a CMD⌘+S shortcut (which is commonly used to save a file).

This is what they show:

It’s not confirmation of an action happening, its sole purpose is to intercept a common habit, and remind the user of it's irrelevance.

2. Types of task

Imagine that you’ve been sent to the supermarket with a list of things to buy:

  • 6 Oranges
  • 2 pints of milk
  • Discover new culinary preferences
That third one would probably trip you up: how can you achieve that right now? Does this require trying a new food every day?

On Credit Karma, “4 things to do” is positioned as a to do list.

But it’s perhaps too crude to bucket everything together, because there are actually two distinct types of action available:

  • ☕️

    Completable task

    A specific action that you complete once, like registering on the Electoral Roll.

  • 🧠

    Habitual change

    An ongoing change of behaviour, such as paying your credit balance on time.

Not only does this make it difficult for someone to ever feel like they’ve truly completed their to do list, but it trips over itself when the tasks disappear.

e.g., when the “check your addresses are correct” task disappeared, without me even opening all of the tabs that'd be required to complete the task.

If it were up to me, I’d separate these into more distinct buckets:

  • 2 things to do today.
  • 2 new financial habits to adopt.

3. Not just a CTA

Credit Karma highlights registering on the electoral roll as a 'high impact' task. And, it's relatively easy in the UK—you can do it all online.

It's almost the cardinal rule of UX: if you want the user to complete a boring task, then remove as much friction as possible. 

So why doesn't Credit Karma provide you with a link to start the process?

It's a confusing omission, and one that rivals Clearscore picked up on.

But there's an important lesson here: it's not just a shortcut (to the Gov.uk website), it's a means of starting the process.

And it's been reliably demonstrated that once a user has started a journey, they carry a willingness to continue. The act of clicking the button is self-motivating.

💡 Why is this motivating? One reason is that people dislike contradicting themselves, and once they've self-identified as someone who will complete that task, they have a tendency to lean into that role.

4. Facepalm architecture

When browsing through your credit report, you can click to view a detailed breakdown of your individual banks.

Below is a screenshot of that individual bank summary, and I have an experiment to try—during which I want you to rely on your intuition.

Looking at this screen, how would you go back to your credit report summary?

Throughout testing, I kept hitting the backwards arrow in the top-left corner. As you may have guessed, this was incorrect, as it takes you back two pages, to the main 'credit' tab.

It totally breaks convention, and therefore expectation.

Frustratingly, it's the cross on the right-hand side that you need to press.

To be clear, the lesson here is not that crosses always need to be in the top-left, but rather that by having two levels of 'back' in one view, you'll create frustration.

5. Conversational titles

Imagine that you've been sent to an unfamiliar supermarket again, but this time with a very clear list of things to buy.

You glance down one of the isles, and see the following:

Most people would find this disorienting. Why are the canned foods in the same isle as a 'bucket of stuff'?

And what is that bucket of stuff? What lives under 'Ketchup and savings'? Is that savings only for Ketchup, or does it include other items?

Despite being an exaggerated example, it demonstrates a potentially dangerous trend: overly-conversational content.

In an attempt to appear more human, product teams will often add personalisation into their app.

For instance, here are 5 different variations of the same instruction:

  • ✏️

    Default

    Enter your email address.

  • ✉️

    Less friendly

    Enter email address.

  • 👋

    Friendly

    Hey Peter, enter your email address.

  • ❤️

    Too friendly

    Great to have you around Peter, firstly, what's your email address?

  • ⚓️

    Other personality

    Yaar welcome aboard Peter, what's ye email address sailor?

Having a unique tone of voice is great, but when taken too far, it whiplashes into friction

i.e., as you trade clarity for personality, things get harder to digest and understand.

It's more difficult to be consistent, when embellishing instructions and headings with personality.

And this is something that subtly increases the 🧠 Cognitive Load when trying to learn how to use the Credit Karma app. For example:

💬 Conversational titles

👀 Decoded explanation

Your smart money hub

The hub for suggestions of how to save money, such as switching expired phone contracts.

UX cheatsheet

✏️

Things to try:

1.Un-contextualised headings

Make an un-contextualised list all of your headings and titles, and scramble the order—I've created a template for you. Then, ask non-team members (e.g., family and friends), to guess what they mean.

💬

Conversations to have:

1.To-do lists

If you have any kind of 'to-do' lists (e.g., onboarding tasks, profile creation), are they completable tasks or habitual? Is your design actually suited for that type of task?

2.Can we be more helpful?

Are there any shortcuts that you can give your users, to save them time outside of your product? (e.g., a link directly to an external resource they could use).

Things to avoid:

1.Double 'back' buttons on modals

Avoid having two 'back' / 'close' functions in view at once. If you're showing a modal, make sure it hides the 'back' button on the underlying page.

Credit Karma: Double back button

Credit Karma show both an 'X' (to close the modal), and a 'back' to go back to the main navigation.

This creates unnecessary confusion about which to press.

Inside some of Uber's guides, they'll show this double 'X'. Which do you press?
