Theory and Practice An INFJ’s intuitive focus also means that he’ll tend to have his head in the clouds as opposed to being a more down-to-earth personality type. Sensors tend to be grounded in the here and now and, as a result, are only interested in theories so far as they apply to the present and make life better. Intuitives, such as the INFJ, however, enjoy theories for their own sake. They’ll worry about getting around to the application later on.
