To give an example. Suppose someone wrote a very long post under the heading "The illusion of superiority" and it began:
After reading dozens and dozens of posts and hundreds of comments, it seems to me that a great many people on this forum think that since they figured out TTATT, they must therefore be a highly intelligent and incredibly knowledgeable individual. Let me take a moment to congratulate everyone. Its a big step to figure this out - I know.
That said, IT DOESN'T MAKE YOU A GENIUS! Nor does it make you a knowledgeable person. In fact, there is a great number of people on this forum who don't seem to understand even the most basic tennants of science. Ironically, the people who don't understand science are usually the quickest ones to accuse other people of being "unscientific." And, I would venture to guess, almost everyone who has read this far is currently nodding their heads and thinking to themselves - "Yes, there are a lot of people who are bad at science on this site." - without even the slightest consideration that they may fall into that catagory.
What do you think about this way of writing it? Do you wonder if the person thinks you belong in this category of unscientific individuals who have deluded themselves into thinking they know something? Do you think this is an example of good/efficient scientific communication even if the critisism is correct?
Instead, suppose you started a thread under the heading: "Something interesting about [eg.] thermodynamics", and gave an example of something you had observed many people got wrong, why it was wrong and what the right answer was. I imagine you wouldnt get a lot of pushback, that many would find it interesting to read and all would think you knew something about thermodynamics.
On the other hand if you consider a 2 page angry rant on the subject that people know jack shit about science even if they think they do; well, that person may or may not know something about science but he sure haven't demonstrated it; at the very least few are likely to read the thread and come away thinking "geh, i should really learn about thermodynamics!"
