If you’re looking for an in-depth tool to understand your thinking style, identify emotional blind spots, and make more balanced decisions, consider the Acumen Capacity Index (ACI) assessment.
Here’s what you need to know about ACI, from its scientific foundation to how you can apply it for real-world results.
Key Takeaways
- The Acumen Capacity Index (ACI) measures how a person thinks, processes information, and makes decisions.

Understanding how people think leads to better problem-solving, communication, and performance.
Here’s Everything You Need to Know About Acumen ACI
From the benefits of the assessment to the ways individuals and organizations can benefit from its insights.
What is the Acumen Capacity Index (ACI)?
The ACI assessment measures how a person thinks and processes information. It is based on the science of axiology, the study of values and judgment.
TTI released its version of the ACI assessment in 2010, building on the Hartman Value Profile (HVP) and its established methodology.
At its core, axiology provides a framework for understanding how individuals assign value, make decisions, and interpret the world.
“Axiology gives us the means to recognize and fulfill the good within each of us, thereby enriching our lives.”
Another way to put it is this: the axiology behind the ACI “gives us the means to recognize and fulfill the good within each of us, thereby enriching our lives.” From Freedom to Live: The Robert Hartman Story.
Speaking of Hartman, let’s learn about the man behind the concept.
What is the Science of Axiology Based On?
The ACI assessment is based on the work of Robert S. Hartman, a philosopher and founder of formal axiology.
Hartman pioneered the science of values, aiming to define what makes something “good” based on how well it fulfills its intended purpose.
His work continues to influence modern tools like the ACI assessment, which apply these principles to human decision-making and perception.
