That is what I was getting at. I do not believe it is even possible to communicate in a way that everyone will understand or comprehend consistently.
I see situations all too often with both written and verbal communication where what is communicated to someone and what they *think* they hear (and thus act upon) are so different that it is shocking. Barriers to communication (linguistic, cultural, etc), assumptions, personal biases (pathologies, agendas, etc), and various biases (cognitive, cultural, etc) are powerful constraints that make the perfect conveyance of ideas and information exceedingly difficult if not impossible. While the desire to communicate with 100% clarity is a reasonable desire, but I do not believe that it is a realistic desire.
From a business perspective, hypothetically speaking if I can spend $1,000,000 to communicate effectively to 60% of my customer base and generate $10,000,000 in profit OR I can spend $4,000,000 to communicate effectively to 100% of my customer base and generate $13,000,000 in profit which is the better business decision? In my opinion, the former is better as it makes the financial performance look stronger due to higher ROI ratios (900% ROI vs ~225% ROI). There is a point of diminishing returns where businesses make a decision on what is “good enough”.
