Tempered radicals are informal leaders who quietly challenge prevailing wisdom and provoke cultural transformation within organizations. They embody contrasts by having firm commitments but flexible means, working alone yet uniting others. Tempered radicals effect gradual change through tactics like disruptive self-expression, verbal jujitsu, strategic alliance building, and being opportunistic. Disruptive self-expression in language, dress or behavior can slowly change workplace culture by inspiring discussion. Verbal jujitsu redirects negative statements into opportunities for positive change. Strategic alliances enhance legitimacy and power to implement change.
