## WHAT IS IT?
Most user-generated content (UGC) do not take responsibility for the accuracy of the information submitted by the lay user. Since everyone consumes copious amounts of information online, it’s only a matter of time before someone is deceived by bad information. This model simulates user consumption of data, and whether or not the user becomes deceived when consuming a piece of bad information. The deceivability of the users is based on Ebbinghaus’ Forgetting Curve.
 
## HOW IT WORKS
We will describe how the model works in 3 parts: Components, parameters (Forgetting Curve), and process flow. Further model description information can be found in the final project report. 

### How the model components work
Information hubs (red squares) represent any centralized system that distributes information to its users and to other hubs. The purpose of the hub is to route “infobits” and filter information based on parameters.  A hub can connect to one more hub to exchange infobits.

Users come in three flavors: Blue (never deceived), Red (deceived), and Teal/Green (recovered). A user represents any individual that that consumes information on a regular basis. In this model, the users only connect to one hub for information - this is purely for visual and computational reasons. Users go through a “fast-and-frugal” selection tree to simulate user behavior. See report for more information. 

Infobits (green or red turtle) is any piece of consumable information a user may find online - news article, facebook post, tweet, blog post, etc. Infobits get assigned to a hub at the beginning of each cycle. The amount of infobits that reside at the hub does not represent the overall information available, but rather the information that will be consumed. You have to switch the “seebits?” switch to ON to see these turtles.

### How the Ebbinghaus’ Forgetting Curve works
Ebbinghaus’ Forgetting Curve is R=e^(-t/M). R being memory retention, -t being time in days, and M being memory strength. In the model, you can select a user’s initial memory strength, it’s memory strength after recovering from a deceived state, and education rate, r, which modifies -t to (-t/r). 

### How the process flow works: 

Very simply, the process is as follows: 

1) Hubs/users get created and linked
2) Infobits get created and assigned to hubs
3) Hubs decide filters
4) Users decide whether or not to consume
5) Forgetting Curve formula calculated for user
6) User gets state change: Gets deceived? User already deceived? User recovers? 
7) Consume infobit - infobits die when consumed. Data transfer is one-way from Hub -> User. 
8) Start next tick with step #2. 

Fully detailed Process Flow Diagrams and explanations are found in the report.

## HOW TO USE IT
Start by selecting what you want to display. Since turtles can only show one label, you have to choose either SeeMemoryRetention? Or ShowDataUse? As the label. Set the percent increase for infobits, maximum run time in days, and the rest of the parameters. Then hit setup and go. A thorough description of parameters can be found in the report. 

## THINGS TO NOTICE
Add-users-per-tick slows down the model tremendously. Also, if %-infobits-increase-per-tick is increased past 1%, the model eventually becomes VERY slow as infobits increase exponentially. Additionally, users only connect to one hub, and hubs only connect to one other hub - for aesthetic and computational reasons. It takes too much computing power to connect users to more than one hub.
