… there is always pressure to block criticism: to shut off alternatives, shelter the familiar, stifle the imagination. Criticism is, after all, no fun for its targets. No one wants to be a failure, even a relative one. So reactionaries who fear disruption, technocrats who want to pick winners, and self-interested parties who want to shut out rivals can all be counted on to try to limit criticism and competition. The ability to resist this collusion against new ideas is perhaps the single most distinguishing feature of dynamic systems.
