If sortition were issue, rather than term-based, I'd imagine you could use something like a sequestration process for selectees, combined with independent oversight and public transparency rules for the organizations creating prep materials.

It'd be even easier, since the decision makers they were attempting to influence wouldn't have any need to worry about the appearance of propriety to secure reelection, and would be less likely to have a pre-existing set of biases.

They're also more likely to lack knowledge on the things lobbyists will attempt to lobby them on.

Already lobbyists try to run "education programs" with representatives as a means of influencing them (which works rather well). That tactic would be a lot more effective if representatives were perpetually lacking in knowledge about relevant issues.

And I'll bet a lot of these randomly selected representatives will choose to be educated by the group that takes them to a fancy dinner and ball game after, or has donated money to their church rather than the one operated by the local chapter of a perpetually underfunded Walmart Union who offer stale cookies.

All of these things can be mitigated with stricter antilobbying laws, but then again, so can our current problems.

I don't see the problem as necessarily being worse with randomly selected representatives, and in some aspects it may work better (randomly selected hippies will tell big corps to take a hike) , but I don't see it as solving the problem structurally.

Good question. Does someone know how sortition helped fix the oligarchy problem in Ancient Greece? I can't find an immediate answer on wiki, even though it claims that.

Sortition was an indelible feature of Athenian democracy but it was not its decisive characteristic. That would be that the assembly was sovereign, and that it was not representative. Any citizen could participate in any given meeting of the assembly, make speeches and vote directly on the issues. The discussion here assumes sortition to select a representative body. Sortition in Athens was for bureaucratic office and for juries, not for the assembly.
