impact-of-hypocrisy

Source code for simulations presented in "The impact of hypocrisy on opinion formation: a dynamic model"

Building the executables

1. Install GCC (Linux/Windows) or XCode (Mac).
2. Install the GNU Scientific Library, see https://www.gnu.org/software/gsl/.
3. In a terminal, run these commands.

git clone https://github.com/mgastner/impact-of-hypocrisy.git
cd impact-of-hypocrisy/
make

This will build two executables: bvm for the Basic Voter Model and cvm for the Concealed Voter Model.

Using the executables

Basic voter model

./bvm n_run rc n nr_init (seed)

where

• n_run: number of runs
• rc: rate of copying a neighbour
• n: number of agents
• nr_init: initial number of red agents
• seed: seed of the random number generator, automatically chosen as system time if left empty

Concealed voter model

./cvm n_run rc re ri n nr_ext_init nr_int_init nrr_init (seed)

where

• n_run: number of runs
• rc: rate of copying a neighbour
• re: rate of externalization
• ri: rate of internalization
• n: number of agents
• nr_ext_init: initial number of agents whose external opinion is red
• nr_int_init: initial number of agents whose internal opinion is red
• nrr_init: initial number of agents whose opinion is red, both externally and internally.

Output

• observed fraction F of runs in which the red opinion won
• predicted fraction m of runs in which the red opinion won
• observed mean consensus time with 95% confidence interval
• predicted mean consensus time
• During the first run, the fraction of red agents as a function of time is printed to the file dynamics.dat.
