Trust and Authority System
Or, a deeper look at inter-personal relationships
One of the most interesting aspects of this site is the
relationship dynamics between users.

Wait a second…

So how are we supposed to be able to design a system that we have trouble understanding in the first place?
Our suggestion:

Hire a psychologist.

Hire a psychologist.
But since this probably isn’t the solution you were looking for…
Our first priority is to design the system such that it is flexible, and can be changed once real users start providing real data.

Especially since a team full of psychologists probably wouldn’t get it right the first time either…
1. TRUST
Two forms of trust
What the user sees
What the system calculates
Two forms of trust
What the user sees“I trust the user this much.”
What the system calculates“We think you might be interested in this user.”

“I don’t know whether or not to trust this user.”Default Value
“I would trust this user with my life.”
“I don’t trust this user one bit.”
“I trust this user.”
9 Levels of Trust
Simple to the user
More levels of trust than distrust
Most values between 2 and 6, so these are close while ends are further apart
9 Levels of Trust
Besides giving us information,
Allows the user to organize his own information as well
Not all people will utilize this system.

LazinessDoesn’t care
Chooses not toCan’t find/understand it
(Shouldn’t be a problem if we design the website properly)
So, how do wefix this?
So, how do wegather information?
So, how do wepresent interesting
content?
So, how do weestablish relationships
between people?
2. IMPLICIT TRUST
If a user doesn’t tell us how much he trusts someone, we have to guess for him.
Page views
Good (or bad) ratings
Comments and other interaction
Calculate and apply small deviations to the current trust level
Use this value in all calculations, such as search results
This value is never shown to the user!
Addresses not only those who never set trust levels, but also:
Trust levels that haven’t been updated in a while
Trust levels that are inconsistent with other information
3. AUTHORITY
Ideally, users would have an amount of inherent trust.
Because this is how it works in real life.
Someone has inherent trust because:•A lot of people trust him•He is in a position to be trusted
Someone has inherent trust because:•A lot of people trust him•He is in a position to be trusted
This is where authority comes in.
A self-selected, self-correcting, system
An author, when posting content in an area, is prompted to indicate his own level of authority
There’s an incentive to tell the truth:•If you lie, people will distrust you!
A self-selected, self-correcting, system
If a user is not trusted enough to support his authority, he may be dropped down a rank
If the user is trusted by a number of people, it may suggest that the user move up a rank
This is affected by trust, ratings, views, and possibly peer reviews (more on this in a moment)
Elitism
A system of our nature will create strong relationships, and high quality authors will emerge from the start
Newer users will have a tough time breaking into this network, however
By allowing a user to designate an appropriate authority level, he can be found early on
Perks:
Perks:Influence
Perks:Higher search results
Perks:$$$$$
Management by Admin
Always better to have more eyes (and control)
Can’t guarantee people will use trust and rating systems
Might want to require Admin approval for highest levels of authority
Also, Peer Reviews
High-authority users can review other authors’ content, and suggest a higher (or lower) authority
Reviews should be well-written, high quality feedback provided by a reputable source
A quick way to move up through the ranks

Summary
•A network of people, who form relationships and indicate how much they trust each other, both for their own records and for our information gathering.Trust•A system of implicit trust, that is able to infer relationships that aren't directly stated, using other information that is collected.
Implicit Trust
•A self-selected, auto-correcting authority system, that rewards the users that deserve it, and allows new users to make a difference.Authority
•A system that is extensible, with the ability to add, remove, and modify the types and ranges of values of relationships, that adapts to new forms of interaction between people, and is as dynamic as the relationships it serves to represent.Extensibility
