tics to be clear, thorough, and consistent-nothing,

that is, that requires reality to conform to theory.

If you wanna do block of 4:

theory: _______
reality: not clear, thorough or consistent

So theory (blank) should be the opposite of unclear, not thorough and inconsistent

If you wanna do support/contrast:

  1. Regardless of → contrast
  2. RHS says “politics is not clear or consistent” → positive
  3. LHS needs to be negative and convey the idea of clear/consistent

Or,

  1. “-” is a support
  2. RHS says that reality does not conform to theory and LHS needs to support this
  3. LHS currently says that politics in reality is inconsistent/unclear, and theory is ____
  4. In order to convey the idea that theory doesnt conform to reality we need theory to be opposite of reality politics
