But even the quoted text said that even if the iee understands the benifits of being firm and direct with others, it's still difficult for them to do.
If the person is looking at something from multiple povs, then they aren't likely to stick with just one of those povs enough to be direct or firm about it. Unless it's something that they very firmly believe in...which for NeFi is more likely to be the value of looking at something from multiple povs.Leaving too many windows open and looking at things from different angles doesn't necessarily imply nor result in indirectness and not being firm, if that's what you're suggesting.
Also, because NeFi don't tend to have strong categorical ideas, that makes it harder to describe what they are thinking, which naturally leads to round-about descriptions. Add in their tacticalness and there's an additional experimental approach to their methods that are prone to change as circumstances and feedback results alter the initial ideas. Being firm and direct requires choosing ONE out of many.
So you're right in that open windows and different angles doesn't necessarily imply indirectness and not being firm, but it sure makes it difficult and stressful to consistently choose and stick with ONE out of many.
