I am always acutely aware of how I am being received. If I notice someone glance away for even a second, I speed up the explanation, change the subject or inject something humorous in to draw everyone back in and get everyone commenting and talking back.
This is very, very true for me, I am very aware of picking up non-verbal cues from others, and shifts in dynamics of a group....I know when someone is getting bored, or 'humouring' me.
And, I stop, cuz it feels like wasted breath and bullshit social niceties, so I'll try another way of presenting my material. There's a 1000 and 1 ways to present something, and the more ways you can accurately do so, the deeper the understanding you have of the topic. And the curiosity in the knowledge is too much for me to hold - I must share.
While my INTP friend is just.........dry. He knows what he knows and that's that. He has a monotone and it's the same with the presentation of the topic, and thus, the resulting engagement in the topic is also the same theme - dry. Drought. I feel parched at the end, like, I need water as my mouth has turned to cotton after that long of inaction.
My brain too, a bit.......cuz I think the best way to stimulate the brain [others, audience] is active engagement, not passive transfer of knowledge, which is the diff. b/w the ENTP way and the INTP way. Lead with Ne versus Ti.
If the topic is already an interest of mine, I have to put in conscious effort to 'pay attention' when my INTP friend speaks, and I'm always glad after, cuz he speaks to such depth and precision on the topic....but it's an active EFFORT to pay attention.
While, when I may present on the topic, my way promotes active ENGAGEMENT. (basically, ENTPs 'care' about the audience, INTPs don't)
