&gt; The law of large number makes sure the randomness in sortition is limited and predictable. Whereas with elections there is a big number of arbitrary factors that greatly can influence the results.<p>With elections, there are constraints which make deviations from the preference of the electorate less likely the greater the salience of the issue is. Sortition distributes the <i>issues</i> on which the decisionmakers deviate from the represented population randomly, which means that salience of the issue does not affect the likelihood of deviation between the decisionmakers and the represented population.<p>This is a significant weakness in sortition compared to elections, that needs to be weighed against whatever advantages are identified for it.
