Ok as a college prof who teaches language (Intensive ESL, college reading, basic writing, second-year composition, graduate courses in teaching ESL, teacher certification in Cross-cultural, Language and Academic Development), here's the value of Gardner's multiple intelligences: Along with personality types and learning styles, preference for indoor or outdoor work, etc., one's varying levels of ability to read and write, analyze and synthesize (do critical thinking), get along with people, follow instructions, keep track of details, create, mediate, visualize, be dextrous or introspective or social... are all skills that can help guide people choose careers that they will excel at, or at least be competent in. Getting an accurate impression of these abilities (multiple intelligences, according to Gardner) also helps people focus clearly on which talents to develop further as well as which areas to try to bring up to a basic level of competency. It's extremely useful.
