It may come as a surprise that one of the lesser-known personality tests out there is actually the only one based on actual brain chemistry and designed with the idea of helping you find the best mate in mind. It’s called the Fisher Temperament Inventory (FTI), and it was created in 2005 by author and biological anthropologist Helen Fisher, Ph.D.
Through her research, she was able to identify four brain chemistry systems that are each linked with a collection of personality traits. And when you understand your specific brain chemistry, you can better understand yourself (and others).
Once you answer the questions, the test tells you which chemicals are more dominant in your brain and, subsequently, what your personality is like as a result. This will help you determine your personality type and identify which personality type will be your best match and which personality types you definitely need to avoid!
Dopamine (Explorer)
If your test shows dopamine dominance, you would be an “Explorer.” According to Fisher, Explorers are risk-takers, novelty seekers, and mentally flexible people. They’re curious, spontaneous, and energetic, and above all, they are creative. They don’t like too much routine and are always ready for the next adventure. In additional research, Fisher has found that those with dopamine dominance typically prefer to date people who are also dopamine dominant and should usually avoid dating Builders.
Serotonin (Builder)
Serotonin types are known as “Builders.” Builders love structure and routine. They’re traditional and conventional, conforming to social norms, including following the rules and respecting authority. They enjoy plans and schedules and are generally more concrete thinkers as opposed to theoretical. According to Fisher, there’s also a tendency for Builders to be traditionally religious. Those high on the serotonin scale usually prefer partners who are also high on the serotonin scale and should usually avoid dating explorers. These two types are quite opposite!
Testosterone (Director)
Those with testosterone dominance on the questionnaire are called “Directors,” and they do well with “rule-based systems,” or things like engineering, mechanics, computers, and even music, Fisher says. These people are analytical, logical, decisive, and have good spatial awareness. They’re also tough-minded, direct in their speaking, and often skeptical. Directors and Negotiators typically choose each other for romantic partners.
Estrogen (Negotiator)
And lastly, Negotiators are those whose test showed estrogen dominance. Negotiators are conceptual thinkers, and Fisher notes they do well with ambiguity and long-term thinking. They are imaginative, usually have strong social skills, including an ability to read people’s body language and tone, and are empathetic, trusting people. They are also typically emotionally expressive, where Directors typically are not. Again, Negotiators and Directors usually go for each other romantically.
