  We study the roles of social and individual learning on outcomes of the
Minority Game model of a financial market. Social learning occurs via agents
adopting the strategies of their neighbours within a social network, while
individual learning results in agents changing their strategies without input
from other agents. In particular, we show how social learning can undermine
efficiency of the market due to negative frequency dependent selection and loss
of strategy diversity. The latter of which can lock the population into a
maximally inefficient state. We show how individual learning can rescue a
population engaged in social learning from such inefficiencies.
