we don't talk enough about how smart dean winchester actually is so here's thread about it
he rebuilt the impala from the ground up many times and he knows his way around an engine
dean created an electromagnet to wipe out the ghostfacer's hard drive
he reads and understands vonnegut and bukowski
he made his own sawn off shotgun when he was just a child and he also built EMF reader out of a walkman
he's very strategic, practical, and clever when it comes to hunting - for instance he drank phoenix ash and tricked eve into biting him in order to poison her
he is actually smart enough to fit in anywhere - when he and sam went to prison he adapted so quickly that he even started his own business there within a few days
he identifies patterns very quickly and efficiently
he knows how to create molotov cocktail
oh and by the way, his knowledge of the lore was always impressive
he's actually very smart, he just doesn't usually like to show it
