  • What kind of data is in a personality profile?
  • Where does Crystal get this data?
  • How do I know that the personality profiles are accurate?

We have answers for each of these. Let's go through point by point...

What kind of data is in a personality profile?

When we refer to 100M+ unique personality profiles, we're specifically talking about over 100M DISC types matched with unique email addresses

What is DISC?

DISC is a well-known behavioral model commonly used in management, communication training, leadership development, and counseling to help people understand and communicate with each other better. 

At the core, DISC identifies 4 primary types of behavior (dominance, influence, steadiness, and calculation) and gives us a common language to describe each of them. Everyone exhibits each of the 4 types, but the amount of each varies from person to person, giving them a unique DISC type

How does DISC help me?

When you can accurately identify a person's DISC type, it tells you a lot about how they like to work, how they communicate with others, what motivates them, what makes them uncomfortable, what kind of emails they like, and more. It's an incredibly powerful, but simple framework for understanding how someone behaves.  

Crystal profiles contain all of this information and more, so you can understand anyone on a deeper level - colleagues, friends, customers, prospects, etc. 

How does Crystal get this data?

Crystal's personality data comes from three main sources:

  • Assessments taken on our platform.
  • Information from social media, articles, blogs, and other public resources. 
  • Data provided by our users.

We'll walk through each one by one...


When you sign up for Crystal, you can take a free DISC personality assessment and invite your whole team to do the same. Thousands of people complete assessments on Crystal every week, helping Crystal get smarter and build a more accurate dataset. 

Public data

When Crystal does not have a completed assessment for a person (i.e. most people you look up), we aggregate public data and analyze the person's DISC type. 

This dat comes from social media, articles, blogs, and other public resources and our analysis is performed by our personality detection engine (for the nerds out there, we specifically use machine learning techniques like bayesian statistical analysis and supervised neural networks to analyze writing style and other attributes). 

Public data analysis is never perfect; it's more of a best guess. So, we always report an accuracy confidence of 0-100% to tell you how confident Crystal is of the profile's validity. 

User-provided data

As a Crystal user, you can get personality profiles instantly for the people you know by connecting your email contacts (Gmail) and social media connections (LinkedIn). 

When you connect your contacts, you help us expand and improve the personality database with more accurate information, and also help us deliver profiles more quickly with a higher email match rate. 

You can also create your own profiles with resumes, emails, and other written text using the Text Analysis tools.
