It is wonderful that you have all discovered personality testing.
Whatever this signifies to you. Perhaps it means that you have obtained an insight into your own typological traits or that the personality systems assist you in understanding others.
However, it is imperative that you take caution when you are understanding what these types indicate.
1. These are not explanations of you as a person:
What these typology tests indicate are generalised patterns of thought and behaviour amongst a tested population. They do not explain away your very self.
2. There is no absolute truth about you.
The common features of traits are numerous and there are many aspects of the human personality that are not measured by MBTI/Enneagram/SLOAN. You do however share some common traits, which manifest themselves to varying degrees and with varying significance.
3. NO TYPE IS SUPERIOR TO ANY OTHER!
Remember, these traits only indicate how you may/may not operate consciously/preconsciously. The tests are fallible and the descriptions alone do not support your judgements of yourself or others. Take this only as a tool that may or may not assist you in your intra/interpersonal relationships.
Here is a list of biases that may assist you in overcoming fallacies that relate to the tests:
Please be aware of biases within self-evaluation. In addition the biases which may stem from such a measure:
Barnum effect (also known as the Forer effect):
This bias relates to when a person validates a type assessment based on subjective responses.
This bias relates to making choices based on information given by those who present suggestion of authority or prestige.
The bias of attempting to minimise conflict or disharmony through group decision making or favouring agreeableness whilst ignoring dissent.
Bias Blind spot
A behaviour of compensating for one's own held beliefs or biases. A self-serving bias which rejects contradictory information.
A bias of ascribing positive assessments/attributes to a choice in retrospect, so as to subjectively validate that choice.
A reflexive behaviour of rejecting new knowledge in favour of thought habits, beliefs or opinions/methods.
Wishful thinking bias
Forming beliefs or making decisions based on what is pleasing to imagine as true rather than by support of evidence or rationality.
Viewing choices or events as predictions/explanations based on past events or hindsight.
Viewing information to be correct because of the personal significance to oneself (not with substantial evidence)
Personal attributes, unacceptable thoughts/emotions are projected onto another or a group. This can apply to types when one believes a type description shows an inclination for others to behave in a different manner.
System Justification bias
This is a tendency to defend or entrench oneself to beliefs that certain systems or beliefs should be considered legitimate or desirable because they are of the "status quo".. This can be applied to over-estimating typology systems or favouring one over others.
Ultimate attribution error
Mostly directed at members of another group (in this case, another type). This can be combined with most of the above biases, in favouring the behaviours described by one type and ascribing negative behaviours to another type in an attempt to justify one's actions.
Please consider these biases when you are considering what to do with the information you obtain from your typing. And don't forget, it is just a description. It does not explain yourself or even indicate who you are, neither motivationally or consequentially.
