Clique signal

Belief-tribe signalling (or just tribal signalling) is the practice of signalling one's membership in a belief tribe, typically one or more of the following methods:

• firmly proclaiming one's fixed beliefs to others (verbal signalling)
• employing particular words or phrasings common only within the tribe (lexical signalling)
  • Example: creationists often talk about "evidences" instead of "evidence"
• performing various tribal customs – wearing certain clothing, performing rituals, etc.
• discriminating against others whose beliefs appear to conflict with those of one's tribe
