$$ m(t+1)\;=\;\tfrac12\,\textcolor{#3288bd}{\tanh\Bigg(\frac{\lambda_{A}\,\rho N\, m(t)+\gamma/2}{T}\Bigg)}\;+\;\tfrac12\,\textcolor{#c2602b}{\tanh\Bigg(\frac{\lambda_{B}\,\rho N\, m(t)+\gamma/2}{T}\Bigg)} $$
two kinds of agent, half each: λA = 1.6 (strongly conformist) and λB = 0.4 (weakly conformist) · mean λ = 1.0
