Complex behavior emerges from rewarding successive small approximations

Evidence

The point was they had discovered shaping: a technique for instilling complex behaviors through simple rewards, namely by rewarding a series of successive approximations of that behavior. “This makes it possible,” Skinner wrote, “to shape an animal’s behavior almost as a sculptor shapes a lump of clay.” — Brian Christian, The Alignment Problem, 660

Categorization

  • DEFINE: Defines shaping via Skinner’s sculptor-of-clay metaphor, which grounds the whole chapter’s technical discussion.
