Life Languages and Myers-Briggs

Comparison of the Kendall Life Language Profile™ (KLLP™) and the Myers-Briggs Type Indicator® (MBTI®)*


Foundation Scriptural Foundation:  Romans 12 and Kendall Life Languages™.  Similar to the Seven Motivational Gifts, but much more comprehensive.  Developed by Fred and Anna Kendall. Humanistic Foundation:  Greek Philosopher Hippocrates’ (460-377 BC) Four Humors (moods based on body fluids), psychologist Carl G. Jung’s (1875 – 1961). Theory of Psychological Type (1921/1971), and interpreted by Isabel Myers and Katherine Briggs.
Purpose Communication Analysis Profile.  Measures communication preferences based on communication characteristics and character qualities.  Measurements show range, intensity, compression, and gaps of each person’s Kendall Life Languages™. Psychological (Personality) Type Indicator. Measures personality preferences and behaviour when preference and behaviour are the same.  Does not measure behaviour directly.
Adaptation Has been secularized to reach secular markets and comply with EEOC standards for government agencies and corporations with government contracts.  Biblical truths and principles are not violated. Sometimes Christianised to reach religious markets and adapt humanistic philosophies to a Christian audience.  Secular theory and philosophy remains the same.
Theory The Kendall Life Languages™.  Are innately God-given.  Everyone has a combination of all seven Life Languages at different levels and intensities.  Each person has a Primary and Last Life Language that does not usually change. Jung’s Psychological Types Theory is a belief that everyone uses four Basic Mental Functions: Sensing, Intuition, Thinking, and Feeling.  The 16 possible Types differ only in the priorities they give to each function and in the attitudes they typically use.
Application Dynamic aspects are more flexible in communication.  A person generally communicates in his or her Primarily Life Language or alternates between his or her Primary and Secondary Life Languages if they are close.  However, everyone can learn to “speak” all the Life Languages.  One can even develop his or her Last Life Language and temporarily use it to communicate.  The more multi-lingual a person is, the healthier he or she becomes in communication abilities. Type theory is based on preferences and is inflexible.  Individuals cannot easily move from one of the 16 Psychological Types to another.  The weaker the scores, the less psychologically healthy a person is.  The assumption is that he or she is less self aware (confusion about preferences), in transition (conforming preferences), or unhealthy.  On the other hand, high scores (Strength of Score) can exclude the other preferences.
Depth More comprehensive and less complex.  Currently, there is only one questionnaire form, which has 115 questions.  The report yields varied scores for the Kendall Life Languages™, 14 additional scales, 14 attributes with one profile report.  Future questionnaires are being developed for children and adolescents. Less Comprehensive and more complex:  There are at least ten different MBTI question forms (A, B, C, D, E, F, G, AVA, M & Q with about 93 questions each. Yields only four dichotomous (bi-polar) scales)
Accuracy Specific characteristics make closer matches with all kinds of people.  The Kendall Life Languages™ in different combinations and levels of intensity provide extremely close matches of an individual’s communication style.  Instead of putting different people into only 16 boxes, Kendall Life Languages™ generates 5040 possible permutations in five levels of score strengths for each Life Language. Generalised characteristics are less specifically matched to people who may be a combination of other factors beyond the limited 16 Psychological Types.
Clarity Easy to understand and interpret.  Report explains results specific to the individual KLLP™ is self-interpretive and self-explanatory. Difficult to understand and interpret without extensive training.  Requires extensive knowledge of Jungian Psychological Theory to interpret.  Generalized to apply only to 16 types of people.
Scope Profiles are more closely matched and reflect the person more accurately in all of his or her environments or settings in all areas of his or her life. Specific to attention focus, information gathering preference, decision-making preference, and organisation preference.
General Scales Three Categories:  Kinetic, Emotive, and Cognitive. Four Preferences on dichotomous (bi-polar) scales for a totally of eight preferences.
Major Scales Kendall Life Languages™:  Mover, Doer, Influencer, Responder, Shaper, Producer, and Contemplator measured on a scale of 0 – 100 and reported as Very High, High, Moderate, Low and Very Low. Sixteen Types (one process is dominant and second process is auxiliary).
Characteristics 14 Attributes, 49 Character Qualities None
Additional Scales 14 Additional Scales None
Scoring Method Computer scoring by Life Languages Institute®, Inc. Multiple scoring methods:  Self-Scoring, Stencil Scoring with Converting Points or Continuous Scores, and Computer Scoring.
Statistics Statistical Reliability Coefficient Alpha scores .90+ on most scales.  Alpha coefficients are no lower than .82 on all scales and up to .95 on Primary, Secondary, and Last Life Languages. Statistical Reliability Coefficient Alpha on best versions of  MBTI Profiles average between .75 and .87.
Reliability Test/Retest Reliability is excellent on Kendall Life Languages™ scales but can change due to the dynamics of the multi-lingual aspects. Test/Retest Reliability on the Four Preferences is 75 – 90 percent.  The weakest percents are on the T-F Scale.
Validity Construct validity show a strong correlation for individual Life Languages.  Criterion Validity for additional scales verified with strong correlation with similar scales on other instruments. Construct Validity strong for correlation for the Four Preferences one at a time, but does not show the 16 Psychological types as dynamic entities.
