The Truity Typefinder Test

The Typefinder is Truity's take on the MBTI test. Unlike most MBTI tests, the Typefinder uses Myers' definitions of the letter dichotomies but then uses factor analysis to determine whether those definitions are empirically valid. Essentially, the test creators have used big 5 techniques to make the test more accurate (accurate in the sense that it measures distinct traits with low intercorrelations). Unsurprisingly, this results in descriptions that are very similar to big 5 descriptions, not because they have simply copied the big 5 (as 16Personalities does) but because if different studies analyse the same subject (human personality) with the same technique (factor analysis) they are likely to come to the same conclusions, even if they started out with a different set of assumptions and suppositions. The big 5 and the Typefinder use different material as the starting point for their theory (Lexical analysis for the big 5, Myers' definitions for the Typefinder) but use the same method to refine and test the validity of that starting point.

Compared to 16Personalities, the Typefinder has a stronger claim to being a legitimate MBTI test because it at least uses the MBTI (in particular MBTI Step II) as its base material. 16Personalities however does not even make the claim that they have used any MBTI theory besides the choice of letters to label each type. This much is apparent from the fact that the Typefinder has no fifth letter (for Neuroticism), whereas 16Personalities does: A feature for which there is no precedent in the original MBTI theory.

The Typefinder may not be the most authentic of the free MBTI tests, but it might be the most scientific. What is lost in terms of "authenticity" is gained in terms of knowing that the metrics upon which one's personality is being measured are legitimate and accurate traits that have been empirically proven to exist. The overall accuracy of the Typefinder is probably similar to that of the big 5, albeit with the exclusion of Neuroticism, which means that the system is necessarily a less comprehensive summary of personality than the big 5.

If you wish to find out your MBTI type, according to the Truity Typefinder, then you can simply disregard the conventional "Tests are inaccurate" advice. Whilst there may be compelling arguments for why taking tests is an unreliable method of typology, those arguments are not valid in the case of choosing whether to take a test or to evaluate yourself based on a summary of those test items. When you take the test, you will be doing the same thing as evaluating yourself, the difference is simply that the test will be using numbers to accurately balance all your answers.

Below are the descriptions that summarise each MBTI trait, according to Truity's system. To re-iterate: these descriptions are not required if you simply wish to work out your own type. Taking the test will yield a much more precise result than simply typing yourself based on these descriptions because the test makes you assign numerical values (it uses a 5-point scoring system) to each item and then does all the necessary number-crunching to give you exact results as percentage scores. These descriptions are simply included as a reference for those who wish to understand the system better or to use it to type others.
