Sensitive and insensitive, how it goes well in corporate?

How can one differentiate a scientist from a sales executive?  Is it simple or difficult?  Do nature has any ‘R&D plants’ and ‘Sales Plants’? It may be very interesting, but nature has finest examples for R&D scientists and sales executives as it has produced such plant species in nature.  Besides proving example for our comparison, nature also has rich teachings/deep message for us.

R&D scientists/people are relatively very sensitive to criticism, exhibits quick response to any stimuli; they are more sensitive as an individual but are relatively very rustic or insensitive to dynamism of time or change.  Personalized sensitivity only they show.  These people always speak the language of micro details and their knowledge disposition than its relevance or need.  In any presentation, scientists talk more about the methodology, experimental design and validation of results than how the results are going to make a difference or overall impact on the organization.  Even for interpretation of some results, they will have the definition, clause and methodologies to follow.   They listen less and affirm more on what they have done.  Any one question their knowledge, they badly get offended.

In the case of sales group, speak more, talk more and create acute need for the product without knowing any details or meaning of what they speak.  They speak the language of how useful the result or product be and how it can take the buyer to reach anywhere & everywhere and for anything and everything.  They do not get bothered or get affected by the criticism or questioning.  Despite all odds and refusal, still they offer their visiting card to the customer to contact them if the customer changes their mind in near future. 

The plant touch-me-not or touch-me-please is a typical example for how scientists at R&D are.  The plant is very sensitive and when touched, folds its leaves. Despite having thorns for its defense, the plant show high level of sensitivity.  So are scientists with high knowledge show restlessness to questions/criticism.  The touch-me-not plant belong to a group of many gigantic trees like rose wood, rain tree etc.  Despite being very sensitive, the plant touch-me-not remains as a very small creeper on the ground, very seasonal and insignificant in the habitat.  This is how in general; the R&D people exist in most corporate.  Because they are over sensitive, they never grow beyond the size of a touch-me-not plant, like how the plant despite being a member of a family of huge trees remains very small.  

The sales people are like horsetail or bindweed.  They are force to reckon with in corporate.  They may appear to be insensitive, but are extremely sensitive.  Because of their sensitivity to the need only one may find a sales person promoting automobile spare parts for a while may start promoting drugs the very next day. 

Sensitivity should lead to adaptation other wise one may not grow.  Being sensitive does not mean anything in nature but the sensitivity should help the species to evolve further.  Neither the R&D people in general nor the plant touch-me-not have learned this lesson and that is why they remain very sensitive without much growth or evolution either in nature or in corporate.
