Reputation & Identity


Wednesday 4A

Convener: Sam Smith

Notes-taker(s): Dan Finlay


Discussion notes, key understandings, outstanding questions, observations, and, if appropriate to this discussion: action items, next steps:


Reputation is a predictor of your future behavior.

Reputation is used to engage in a transaction.

Reputation is highly context-dependent.

When engaging in a transaction, you want to disclose the minimum necessary information to establish good reputation to the other person.

“The Principle of Least Disclosure”


Joe Andrieu:

Privacy is about contextual integrity.


Nathan George said some 


There is no one value of reputation, no one credit score.

Even the credit agencies get paid by banks for more context-tuned credit scores.

The value always just being the prediction of future behavior in this context.


Reflexive Reputing:

Reputable events are “Reputes”

A repute is a person (reputer) reputing a reputee.

Whoever is collecting a repute has an implicit repute going the other way.


When Amazon first released ratings, they were simply 5 stars and a comment.

Then people would just mob & vote up their friends & down their enemies.

Then they required you buy the item.

Now they let people rate reviews so that useful reviews can be prioritized to the top.


Kevin Serrano points out:

A political book advocating “questionable things” could still have high ratings, because its readers are self-selecting for people who agree with it.

This is why you really want reputations as published by people ho trust.


Netflix does a good job of “Because you enjoyed…”.  Predicting *your future behavior*.  Your likelihood of enjoying it.


Reputation algorithms themselves can have reputations.


What if Facebook had knobs that allowed you to tune the types of algorithm that forms your feed?  Raise your tolerance for other views, perhaps?


Optimize your feed for the person you want to become.


Once we’re in an open ecosystem, we can create incentive systems for bringing people into other ways of thinking.


You need a reputation for reputations.
