Labor Perception Bias

…why faster isn't always better.

Duration: 2 min

Slide 2

Beat 1

Imagine going to a fancy 5-star restaurant.

You order a rare and complex dish…

Beat 2

The waiter leaves, and then—

Beat 3

—comes back with the meal you ordered just 15 seconds later…

Beat 4

…that'd feel suspicious, right?

Slide 3

Well, it's the same thing with digital products…

Slide 4

Beat 1

Imagine signing up for Hubspot's CRM app and…

Beat 2

…towards the end of the onboarding, you import your 287,539 contacts.

Slide 5

Oof… that's a lot of contacts,

I hope everything goes well… {tap}

Slide 6

Beat 1

—and BAM! Hubspot imports all those contacts in just 0.01 seconds.

Beat 2

…uh… that was it?

Did it work?

Slide 7

Just like in the restaurant example, faster isn't always better.

You could improve the experience by—

Slide 8

Beat 1

—slowing things down to reassure the user.

Beat 2

📌 Labor Perception Bias

People trust and value things more when they see the underlying work.¹

People dislike waiting in general, but if your users have high expectations (e.g., money transaction, migration, analysis, reporting), they become skeptical if the waiting time is too short. That's why displaying a labor screen right after a key action can improve your UX.²

For "benevolent deceptions"³ (fake waiting times), there are important ethical rules. We cover them step-by-step in the bonus at the end of this story.

Slide 9

When you understand the Labor Perception bias, you see its applications everywhere.

For example…

Slide 10

…when you transfer money on Wise.com, you're not just—

Slide 11

Beat 1

—dumped into an activity log.

Beat 2

uh, ok…? Hopefully my money will get there…

Slide 12

Instead of this abrupt transition…

Wise.com shows you—

Slide 13

—a reassuring animation of your money being processed and transferred.

Slide 14

Beat 1

Now, these transition screens may seem like simple interface decorations, but…

Beat 2

…the psychology behind the Labor Perception bias can have a serious business impact.

Beat 3

📌 The ROI of Labor Perception

A well-designed effect can increase your app's perceived value by up to 15%.⁴

The net lift on activation, retention & revenues obviously depends a lot on your context (waiting duration, audience, product, etc), but it's worth testing.

Beat 4

Plus, you can apply this concept to almost every product, so give it a try.

Beat 5

Be careful though…

The Labor Perception bias can be damaging if you apply it incorrectly (e.g., unethically).

For example—

Slide 15

Beat 1

During the 2016 Presidential elections, the New York Times used a live "Election Needle".

Beat 2

Dozens of employees fed new data every 15 seconds.

Their hypnotizing needle conveyed hard work, but—

Beat 3

—this amplified labor perception is not quite ethical.

Could you say why?…

Beat 4

📌 Information vs Fear

Think about it: if the data is updated every 15 seconds, why is the needle jittering 10 times per second?

The answer is simple: this amplified uncertainty⁵ maximizes engagement⁶, page views⁷, time on site, and revenues.

You should use Labor Perception to reassure users, not to manipulate them.

A more humane approach would be to only move the needle when the data is updated (i.e. every 15 seconds).

P.S. we cover more ethical designs in our Product Psychology course (Module 5).

Beat 5

As you can see, it's best to follow clear guidelines with the Labor Perception bias.
