I'm just about to whack one of the sacred cows of the HR world, the Meyers-Briggs Type Inventory (MBTI) test, so if you're a big fan of the MBTI you might want to quit now, o

According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product

I'll summarize the MBTI by saying that it's a personality inventory test based on Jung's theory of opposites. It assumes that there a

Examples of combination products may in

re four important components of a personality and that each is binary: either you are and introvert (I) or an extrovert (E). This means that the MBTI can assign you to one of

lude drug-coated devices, drugs packaged with delivery devices in medical kits, and drugs and devices packaged separately but intended to be used together.

here is enormous increase in the number of combination products entering the market in the recent years. Combination products have proven advantages but fixe

Is it clear to you that this is nonsense? Here are my observations:

d dose combinations are still in the process of convincing regulatory authority on their advantages over the single ingredient formulations.

Combination pro

Jung's theory of opposites was a psychoanalytic theory meant to diagnose and treat psychopathologies, not to categorize healthy people. And even within its realm, it'

ucts have become life saving products for the pharmaceutical companies who doesn’t have many innovative molecules in their product pipeline and have been inc

s now regarded only as a metaphor, not as a reliable personality model.

As far as I know, the MBTI has never been validated to show that it actually measures what it cla

easingly used in the product life cycle management. Even the companies having product patents are trying to extend their product life cycle through the combi

ims to measure. Its correlations against other, more robust personality measurements are very weak.

The questions of the MBTI yield a continuous quantitative value, but

you are assigned to one category or another of a scale based on a seemingly arbitrary cutoff value. So, for instance, my score on the thinking/feeling scale is so close to th

and physically. They need to rightly judge the benefits of the combination products and they have to even look at the risks involved when combining the produ

e cutoff that I'm assigned to different categories depending on how I'm feeling when I take the test.

I've seen plenty of introverts who can be quite extroverted when th

situation calls for it, so whatever else it is, the MBTI isn't a predictor of behavior.

Okay, if that were all of my objections I would just sneer at it as a badly d

ding difficulty in defining their combination products and facing various challenges from selecting a combination to marketing it.

Following aspects would a

esigned psychometric instrument and forget about it. But the world in general, and industry in particular, has siezed on the MBTI as the key to personality and compatibility.

dd to the challenges in developing combination products:

Which markets to tap where the combination products can do fairly well?
Which combination prod

So I have personally seen:

Qualified candidates not hired because "they have the wrong personality profile for the job."
People denied promotions because "th

cts are meaningful and rational?
Which therapeutic categories to select?
Which Combinations can address unmet needs of the patients?
Do combin

eir personality wouldn't fit the executive team."

People moved from software development projects to software quality assurance (testing and bug fixing) because "their p

tions increase the patient compliance?
What would be the developing cost?
How to tackle the risks encountered during combination product developmen

ersonalities are more suited to that kind of work."

I'm not laying these outrages at the feet of the MBTI, it's idiot managers and HR staff who are to blame for misus

t?

As combination products don't fit into the traditional categories of drugs, medical devices, or biological products, the USFDA is in the process of devel

ing it. But the structure of the MBTI is so simple that it seems irresistable to assign people to pigeonholes from which they can never escape because, presumeably, their per

ping new procedures for reviewing their safety, efficacy and quality.

sonality type is fixed.

So personally, I recommend that you stop using the MBTI and that we burn all copies of it, but I know I've got a big chip on my shoulder. If you feel

y and representatives from various regulatory agencies are working out to design the regulatory requirements for manufacture and sale of combination products

you have to rely on it, you should at least combine it with another, better validated, instrument like the Strong Inventory, or use it simply as a starting point for discuss

.

As there is an increasing trend of the combination products companies manufacturing such products should be able to tackle the problems involved in the de

ion and don't take it seriously as a personality measure, or combine it with your intuitive appraisal of someone's personality.

But for heaven's sake, don't stamp a person's

elopment. They need to be wiser in analyzing the market trends and the regulatory requirements.

Companies that provide selfless information through particip

MBTI score on his or her forehead and let it determine the trajectory of their career.

Okay, I'm done with the rant and you can start throwing sticks and stones if you want
