Fair to both

Porcupine takes no sides, and both people get heard.

How Porcupine uses it

Why it helps

People accept an outcome more readily when the process felt fair, and a big part of feeling it was fair is having a voice: telling your side and having it considered. Mediators are bound to impartiality for the same reason. It matters even more for an AI: AI models tend to tell people they’re in the right, and in experiments, people who got that agreement became less willing to own their part or repair things. Porcupine gives each person the same help, doesn’t tell either of them who’s right, and keeps everything shared even-handed.

What we don’t know yet

Most research on fair process comes from legal and workplace disputes, not conversations between people who are close.

The research

Studied with adults in general

Given people’s accounts of things they had done, 11 leading AI models approved of their actions 49% more often than people did, even when the accounts described deceiving or harming someone. In experiments, people trusted and preferred the AI that agreed with them, though it left them less willing to repair a conflict.

Studied with adults in general

In experiments on ways of settling disputes, people judged a process fairer, and accepted its outcome more, when they had control over presenting their own side.

Studied with coworkers

A meta-analysis of 183 workplace studies found that a sense that the process was fair went with greater job satisfaction and commitment and a better view of those in charge, over and above whether people thought the outcome itself was fair.

More research

Studied with adults in general

A review of procedural justice research found that having a voice in the process matters to people even when it doesn’t change the outcome.

Studied with couples

In a study of 31 couples, one partner pressing for change while the other withdrew was common, and who did the pressing depended on whose change was being discussed.

Studied with couples

Across 74 studies, the pattern of one partner pressing and the other withdrawing was linked with lower relationship satisfaction and poorer communication.
