"The meeting of two personalities is like the contact of two chemical substances: if there is any reaction, both are transformed."
Carl Jung
Choosing an MBTI® Web Site
- Be wary if a site says it will reveal answers such as the best job for you, the type you should marry, or the type of employees you should hire.
- Be wary of a site that says or implies some types are better, healthier, or more desirable in any way than others.
- Be wary of a site that presents type preferences as skills, ability, or indicators of mental health or illness.
- Be wary if a site advocates the use of psychological type as a way of putting people at a disadvantage or manipulating them.
- Be wary if a site insinuates that its organization or instrument is the only way to learn one's psychological type.
- Be wary if a site offers a questionnaire that is clearly not the MBTI® instrument, but claims or insinuates that results are the same as would be obtained from the MBTI instrument.
- Be wary if a site offers instruments purporting to measure psychological type yet offers no information on reliability, validity, and research of these claims.
- Be wary if a site identifies types using the same preference names and type codes as the MBTI instrument but does not acknowledge where the terms come from and does not clearly state it is not the MBTI instrument.
- Be wary of a site that uses copyrighted material without permission and/or omits trademark notices.
- Be wary of a site that presents type preferences as fixed behaviors or stereotypes that do not vary among individuals or insinuates that type explains everything about an individual.
- Be wary of a site that says MBTI results are infallible—that the type shown by the Indicator is always the best-fit type.
- Be wary of a site linking another instrument to the MBTI instrument without evidence of a researched validated connection.
