To me, intention and impact are as equally important because of the interpretation that happens in between them.

This is the fax

I work with a lot of people that have completely crap social skills but are otherwise awesome people (computer technicians and geeky manufacturing engineers)
They mean well but a lot of times they will say something that makes sense in their head but have trouble seeing how it can be interpreted in other ways, or even just don't have enough language skills to say what they are meaning without the impact being different than what they want.

In these cases it's your responsibility as the listener to have some patience and ask some clarifying questions to truly understand what they are saying before jumping to assumptions and taking their words at face value, and also to understand that people don't anyways have the skills to correctly say what they are meaning without problems

(It is also the responsibility of the speaker to realize when they are saying word soup and try to rephrase some stuff to help the listener out, which is in this diagram as #1-#4)

In the age of the internet where hundreds of people from all different places, cultures, backgrounds, languages, etc. can all come into one spot and start communicating, immediately looking at the impact of someone's words is a bad setup. If your social skills or language skills are crap then your words will not carry their intended meaning; and so you have difficulty controlling the impact. If listeners fail to look past the impact to try and understanding the meaning, it creates a full communication failure.
