About the Judgement Index

The Judgement Index is the world’s original and best values based assessment tool and has no equal when it comes to identifying and developing the right people. Established in the 1970’s from decades of research by Nobel Prize nominee Dr Robert S Hartman, the Judgement Index has been integrated into forward thinking organisations long before “values” became a buzzword.

It is one of the most highly mathematical, scientific and logically-based assessment instruments ever created, and no other values based assessment comes close to it in terms of depth and sophistication. It empowers you to measure the value system and the judgement capacity and capability of an individual – and it does so with unswerving accuracy.

The Judgement Index is not a personality assessment

People can have pleasing and engaging personalities. They may even have the skill sets, experience, and knowledge your organisation requires. Studies have shown that people are more likely to hire someone they feel is “like them” and we often hear people say they recruit on “gut instinct”

However, if the candidate does not possess good judgement – the determining factor in how every other talent and capability they offer is utilised – then successful outcomes are often not realised.

Personality assessments often categorise people into one of sixteen personality types. In fact, someone who is a CEO and a particular personality type will no doubt find others with the same type serving life in prison. The differentiator between these people, one in prison and one regarded as a success is their judgement. Personality simple is not a good predictor of success – good judgement is.

How the Judgement Index works

“Generally speaking most assessment tools consist of a list of adjectives from which respondents select words that are most/least like them, and are designed to measure “style,” or tendencies and preferences. While they can seem highly insightful — not to mention being widely available and inexpensive — they have some severe shortcomings when used in high stakes applications such as hiring. For one, they tend to be highly transparent, enabling a test taker to manipulate the results in a way that they feel will be viewed favourably by the administrator.” Whitney Martin, HBR Blog Network, August 2014

The Judgement Index is a simple, online assessment and whilst it is not timed, it takes on average around 20 minutes to complete. The participant is twice required to drag and drop 18 abstract phrases into a sequence and order that feels right for them. Because of the abstract nature of the phrases, the assessment forces the participant to reflect and sieve through their own value systems before deciding on an order, which is why it is not possible to predict a desired order and sequence – or outcome.

There are over 12 trillion possible outcomes from the Judgement Index and the results are shown in over 60 different indicators, looking at the participants work and self (personal) side, their internal, external and big picture values, along with their balance of values, and depending on the needs of the organisation we can strip those indicators down to the essential, or provide full written narratives & development workshops as required.

Frequently Asked Questions

So you're telling me you can actually measure judgement? That sounds impossible!

Most people don’t easily understand that judgement can actually be measured, or that it’s something organisations can put into practice and use to improve every day lives. We understand that feeling here at the Judgement Index as we, ourselves were once sceptical and had doubts. So we invite you to talk to us if you do have questions, but we’d like you to understand the importance of being able to measure judgement: If you can measure it, then you can understand it, then you can improve it. If you can improve judgement, then you can improve the world.


How does the Judgement Index work?

The Judgement Index is an online assessment, and whilst it is not timed, it takes on average around 20 minutes for a candidate to complete. The individual quite simply ranks two sets of eighteen statements from best to worst, based on their own unique values. Once they are happy with their decisions they submit their assessment and the highly sophisticated logic and maths used to score the Judgement Index does the work of determining the results.

There is only one Judgement Index assessment, but the results can be viewed in a number of different ways depending on the depth of information required. We have many different reports and score sheets depending on an organisations requirements.

How certain are the results? Can the Judgement Index be tricked?

Because of the abstract nature of the words and phrases in the Judgement Index, it is near impossible to “game”. The phrases give little away as to a desired order and ranking and this forces the individual to reflect on their own value system in order to complete it. The assessment does not ask the individual what they think of themselves, it just asks them to think. There are also in-built validity indicators in the Judgement Index that will suggest a retake if necessary.


What benefit will the Judgement Index bring to my organisation?

The Judgement Index is used successfully to save organisations millions of pounds through a variety of methods; reduced staff turnover, improved hiring practices, improved customer service, increased sales, succession planning, executive coaching, better team decision making, increased innovation, reduced stress, identification of potential burnout, greater strategic awareness, improved company morale, etc. Depending on the needs of your company, the Judgement Index can be applied to benefit all of the above.


Who can benefit from the Judgement Index?

The Judgement Index is effective for anyone. The Index is not a determination of skill set competencies, rational intelligence, or emotional stability; it is a determination of the capacity for good judgement. Improvements in judgement will improve an organisation from the boardroom to the kitchen. Whether your boardroom is an athletic playing field or a construction site, the Judgement Index can help you achieve your best performance. Top ranked teams and individuals use the knowledge gained from the Judgement Index to drive them to the upper echelons of their profession.


Does the Judgement Index discriminate against any particular group of people?

The results are not skewed based on any race, religion, disability, age or gender.


Are there validation studies?

Yes, the Judgement Index has been validated in over 30 individual studies including construct validity, face validity and predictive validity. The compendium of validation studies is available on request. Concurrent validation studies keep the results accurate and fresh.

Has the Judgement Index been approved for use by the EEOC?

The Judgement Index meets the rigorous standards by the United States Federal Equal Employment Opportunity Commission (EEOC) for employment assessments

The Difference

What makes the Judgement Index different?

It differentiates itself by having over 40 years of clinical experience utilising the Judgement Index and developing a comprehensive manual of interpretation. No other assessment company has more in-depth, real world experience.


Is it like Myers Briggs, MMPI or an IQ test?

No. Myers Briggs is a personality profile and an MMPI is used to determine psychiatric wellness. An IQ test measures rational intelligence. The Judgement Index is used to determine the capacity for good judgement. Your results can change over time which is why it is often used as a development tool, and it is also a more accurate predictor of performance than any personality profile.

We already use an assessment tool, why use yours?

The Judgement Index can be used effectively alongside or in conjunction with other assessment tools, or it can be used to replace them. Most assessments are either personality profiles or psychiatric wellness indicators and whilst they may produce interesting information, studies have shown that personality profiles are not reliable indicators of job success. For example it is not difficult to identify excellent managers with quite different personalities. However, any manager with bad judgement, no matter their personality, will not perform as desired.

Getting Started

How do I get started with the Judgement Index?

We suggest you get in touch if you’d like to know more. We can then schedule a meeting with you to discuss you initial requirements and what your priority purpose is for applying the Judgement Index to your organisation, individual or team.

We will be able to show you example reports and also invite you to take the Judgement Index yourself, to understand the user experience, the difference compared to other assessment tools and of course the powerful accuracy of the results.

We have clients who use the Judgement on a “project” basis when needed in their company, and we have clients who use the Judgement Index on a subscription basis for the entire company, both for the existing team and for every new recruit. We can tailor a package to suits your needs so please get in touch for more information.


What ongoing training and support do you provide?

Depending on your requirements, we have a training package to suit. Certain Judgement Index reports require in-depth, face to face training which we can run on a group or individual basis. Other reports need very little training which can be undertaken through our online learning platform. We also have written narrative reports and can create bespoke reporting and feedback if required.

We offer support online in the form of bi-monthly webinars, a client area on our website and regular updates. We also include a twelve month review for any yearly subscription to evaluate the impact the Judgement Index is having on your organisation.
