The opinions on Stolypin's work are divided. Some hold that, in the unruly atmosphere after the Russian Revolution of 1905, he had to suppress violent revolt and anarchy. However, historians disagree over how realistic Stolypin's policies were. Others, however, have argued that, while it is true that the conservatism of most peasants prevented them from embracing progressive change, Stolypin was correct in thinking that he could "wager on the strong" since there was indeed a layer of strong peasant farmers. This argument is based on evidence drawn from tax returns data, which shows that a significant minority of peasants were paying increasingly higher taxes from the 1890s, a sign that their farming was producing higher profits.
