ISFP vs INTP
Here’s how you can connect with your friend better:
Intentionally make your thoughts known to your friend and have an equal conversation with him/her.
Talk about the ‘big picture’
Your friend does not enjoy everyday topics as much as those ‘big’ topics like economics, politics, technology or the like. Try to engage your friend talking about those.
When you are putting forth an idea, refrain from talking about your emotions. Instead be objective and use logical facts.
Don’t take your friend’s words personally
Your friend may say things you deem insensitive or offensive. Don’t take it personally; it’s more often to do with the issue at hand.
Reinforce your points with logic
Don’t back down from what you say even though you are challenged by your friend. Instead, reinforce your points with sound reasoning.
