WHAT IS IT?

This model is created by WANG Chengjun,who focused on the simulation of the spiral of silence theory which is very extensive grand theory.

HOW IT WORKS

Von-Neumann assumed that everyone will be influenced by the media and his social network,everyone who thought their opinion is not a dominate one will fear of being
isolated by the society,so they keep silent,on the contrary,the people who think they are holding the dominate ideas will tend to speak out.

So everyone will be influenced by other people,and this causes the emergence of spiral silence.

HOW TO USE IT

You can moderate the coefficients,control three of their values zero,and oberserve the influence of the forth coefficient on the public opinion.

THINGS TO NOTICE

When you keep the other three coefficients zero(bmedia-opinion-atmosphere, bsocial-isolation-sense ,bexpression-tendency ),but keep the bpersonal-opinion-property equals 0.001,then you can find a neck-to-neck dead lock rather than spiral of silence.

THINGS TO TRY

Try to moderate the vison,which controls how many neighbours everyone will monitor to get an idea of the dominate opinion.

EXTENDING THE MODEL

Netologo restrict the turtles' neibours numbers,but the real network in our daily life is power law,so maybe I will do some mederation latter.

NETLOGO FEATURES

I think the automatic halt and reminding is cool.
