If you are like me, you are weary of hearing about how great diversity is and how it is a source of strength. This is not always the case. Even when we apply diversity to scenarios other than societal, it can be an utter catastrophe.

Companies engaged in manufacturing achieve economies of scale and higher productivity by standardizing and rationalizing manufacturing processes at each of their production facilities. If each facility adopted a diverse approach to product manufacturing, costs would soar, product quality and uniformity would suffer and it would be impossible to implement management policies and business strategies.

Restaurants that serve excellent food achieve their reputation through adherence to strict quality standards and consistency. If each dish were prepared differently every time it was ordered, quality would suffer, costs would rise and customers who do not enjoy playing a culinary version of Russian roulette would probably find somewhere else to eat.

Engineers who design and build massive structures like skyscrapers and bridges ensure structural integrity and human safety by applying specific scientific and mathematical knowledge to apposite materials and processes. Structures that lack uniform design and construction methods or incorporate incompatible building materials will be unstable and unsafe.

Interior designers must coordinate colors, furnishings, artwork and other décor elements to create a space that has a sense of continuity and a pleasant atmosphere. Randomly mixing different types of furniture, color schemes and artwork would result in an unsettlingly schizophrenic atmosphere that would convey a sense of discomfort.

Airline pilot training must be standardized and comprehensive so that pilots are proficient and prepared for any eventuality during flights. Diversity in approaches to training could result in some pilots lacking knowledge or experience that might lead to disaster in the air.

Healthcare in general and surgery in particular require a methodical approach based on the latest knowledge and techniques. Tuberculosis medication is only effective if it is taken regularly for the duration of treatment. It won’t be effective if taken only a few times. Surgeons become experts in their specialization by repeatedly performing operations in the same way. Getting creative with the way an appendix is removed could be a matter of life or death.

In general, education involves repetition and progression through a curriculum from simple to complex. Well organized, highly structured classrooms tend to be the most conducive to student learning. It is difficult for students to learn in an unstable and unpredictable environment.

In the United States, we are told that diversity is one of our greatest strengths. But as Jared Taylor, editor of American Renaissance points out, “Racial diversity is not a strength. It is a grinding, permanent source of conflict and tension, not just in the United States but everywhere in the world where there is racial diversity.”

Professor Robert Putnam of Harvard University conducted research aimed at demonstrating that diversity benefits societies, but ended up proving the opposite to be true. Societies are safer, experience less crime and exhibit higher trust when diversity is low. Putnam postponed publishing the results of his research for many years while he searched for other explanations for his findings. He never found any.

If diversity can be problematic in the areas of manufacturing, restaurants, engineering, interior designs, pilot training, healthcare and education, is it really so difficult to understand how it can also be problematic for society?

And if we admit that racial diversity can be problematic for society, how should we view the forced immigration of “refugees” from the Middle East and Africa into Europe and the United States? Is this a positive development for those societies? Or a destructive force?
