If the ability to detect design necessarily entails a subjective element, then any investigator should be aware of the subjective obstacles that can come into play. And for those who have noticed, I have been laying the groundwork not only in The Design Matrix, but also here on Telic Thoughts.
Let me now add another concept from psychology "“ tolerance for ambiguity. I myself have a very high tolerance for ambiguity, as can be seen in The Design Matrix, but also in most areas of my life. But what is ambiguity tolerance? that Let me just quote from the short Wikipedia entry on this phenomenon.
Ambiguity tolerance is the ability to perceive ambiguity in information and behavior in a neutral and open way.
Ambiguity tolerance is an important issue in personality development and education. In psychology and in management, levels of tolerance of ambiguity are correlated with creativity, risk aversion, psychological resilience, lifestyle, orientation towards diversity (cross-cultural communication, intercultural competence), and leadership style.
Wilkinson's Modes of Leadership is largely based on ambiguity tolerance. Mode one leaders have the least tolerance to ambiguity with mode four leaders enjoying and preferring to work in ambiguous situations. In part this is due to what Wilkinson calls 'emotional resilience'.
The converse, ambiguity intolerance, which was introduced in The Authoritarian Personality in 1950, was defined in 1975 as a "tendency to perceive or interpret information marked by vague, incomplete, fragmented, multiple, probable, unstructured, uncertain, inconsistent, contrary, contradictory, or unclear meanings as actual or potential sources of psychological discomfort or threat."
