Corner Jam

Corner Jam

Asynchronous preference collection that gives leaders confidence and everyone a voice - by making input effortless

The hidden cost of "anything's fine"

When someone says "I'm down for whatever" in a group setting, they're usually just picking the path of least resistance.

Actually expressing a preference takes more effort than it seems. You have to figure out what you want, guess how it'll land, and commit before knowing what anyone else thinks. That's a lot of mental energy for a casual hangout.


Leaders and Followers

We interviewed 6 people and noticed two roles that tend to emerge in group planning. These aren’t personality types, just modes people fall into.

Leaders start the plans and carry the decision burden. They want input but rarely get it.

People don't contribute, yet still critique the plans if they don't like them.
Emilio, leader


Followers have real preferences but don't voice them. They'd rather not steer the group or feel like they're being demanding.

I'd like to share some preferences. I'd rather not be the one who decides though.
Aurora, follower



How might we get full group input without forcing anyone into a role they're avoiding?

Corner Jam

Corner Jam is a feature concept for Corner, a social mapping discovery app. We studied Corner's existing design language to make it feel native - only adding a button, an overlay, and a form

It collects preferences asynchronously through a quick form, then shows "party scores" based on aggregated preferences.

Impact:

  • Full group input (vs. 20-30% in typical group chats)

  • <1 minute per person - 6 simple inputs, no download or account required

  • Data-backed confidence for leaders - party scores replace guesswork

  • No more "down for anything" dead ends - followers contribute without decision pressure

How it works

For Followers
  1. Receive a link (no app needed)

  2. Pick a vibe from image tiles

  3. Set logistical preferences

  4. Submit (<1 minute total)


For Leaders
  1. Tap the party icon on the map

  2. Choose the activity category

  3. Invite friends via app or share sheet

  4. Watch responses come in

  5. Browse with party scores


Scores show group fit at a glance and update live as people respond.

Design Decisions

Group planning has hidden cognitive costs: formulating preferences, anticipating reactions, committing under uncertainty. Each design choice here targets a specific point where effort usually kills participation.

The mental cost -> the fix

Formulating preferences on the spot -> participate when you want to
Group chats put you on the spot. A private form lets you contribute when you're ready, and without an audience.


Describing what you want -> visual tile inputs
Picking from images is faster than reading options, but the real win is that you're recognizing a vibe instead of trying to describe one. Recognition beats recall.


Downloading an app / signing up -> Link-based, no account required
Every extra step gives followers another reason to bow out. Without an app download or signup, there’s as little friction as possible to participate.


Validation

This is a concept that has not been integrated into Corner. We validated our solution by mapping it back to what we heard in research:


Insight

Solution

Leaders want input but don't get it

Asynchronous form enables full group input

Followers have hidden preferences

Private form removes decision pressure

Decision burden isn't shared

Party scores shifts the process away from guesswork


If shipped, we'd measure:
  • % of invited followers who complete the form (target: >70%)

  • Time to complete form (target: <60 seconds)

  • Post-hangout satisfaction (did using Corner Jam lead to better outcomes?)

Reflection

The tricky part of this project was that the friction we addressed is invisible. Nobody thinks "I'm not contributing because expressing preferences in a group setting is cognitively expensive." They just say "anything's fine" and move on.

You can't rely on users to articulate a problem they don't know they have. You have to notice the gap between what people say ("I don't care") and what's actually happening (they do care, they just won't pay the cost to say so). The fix is to make contribution as easy as possible, rather than asking people to contribute more.

Corner Jam adds a button, an overlay, and a form. It’s a relatively small change, but it addresses the complete issue.
