There are three ways to figure that out. The first and probably easiest, although the probably most inaccurate, is online testing.There are a few sites that offer free testing. Our links collection has a few of them, and our own test is available here.
The second way, and more accurate but also most time consuming, is to be tested by a professional MBTI certified test administrator. You'll get your results and they'll even consult with you on the meaning. For more information about this, we suggest you contact the MBTI Foundation for more information about a consultant near you.
The third option is to gather as much information about what the types are and what all the symbols mean and decide for youself. Luckily, with the expansion of the internet, this has become much easier.
For more details about types, we have a collection of profiles here:
