The Comparison system manages the evaluation and categorisation of information by comparing it to other information, including the contents of any active meaning schema.
 Discrepancies originating in the Comparison system could result from the under/over-valuing of particular phenomena as result of using inappropriate comparators or comparison criteria, the inappropriate grouping of phenomena through the mistaken identification of similarities and differences and inappropriate polarised (black-and-white) thinking.
Brookfield's mirrors explore different sources of comparison information and dialogical approaches explore different ways of integrating those potential comparisons
Counterfactual thinking involves comparing the actual situation against a variety of alternative possibilities and appreciative inquiry encourages you to focus on potential strengths to develop rather than just problems to solve
Emotional categorisation can help to tap into the underlying values driving prioritisation and behaviours.
Randomisation can be used to find creative new comparisons
Repertory grid and semiotic square and both-and thinking provide structured approaches to evaluating and categorising aspects of your experience
