From DISC to Insights Discovery, HBDI, LSI, MBTI, Lumina Spark,... each model has its own appeal, benefits and pitfalls. In the world of personal development, I have taken a deep dive into different personality models. 

Why I approach them critically

I have learned to look beyond the surface. There is no denying that many of these models fall short when it comes to scientific validity and reliability. While they can offer insights and are often used in both business and personal development programmes, many of these models struggle to stand up to rigorous scientific scrutiny.

The bidding in the training world

In the training world, we see competition over which model is superior. Marketing often plays a bigger role here than the actual effectiveness or relevance of the model. Models like Lumina Spark have embraced technology, which certainly adds value, but it is important not to let flashy marketing campaigns or technological gadgets overshadow the core of a model.

At the same time, I see the opportunities

Despite these criticisms, I see the potential value of these tools, especially if they are used with an understanding of their limitations. They can contribute to increased self-awareness, better communication and team dynamics.

A plea for balanced use and scientific rigour

While technology and marketing have their place, it is essential not to overlook the scientific basis of a model. Professionals, coaches and trainers need to be aware of the limitations and critiques of the models they use. I encourage an approach where critical thinking and scientific rigour are paramount.
