Hi Talal! I listen to podcasts pretty much all day every day when I'm working, Stuff You Should Know is one of my favourites so with it in mind that you enjoyed that one, here are a few of my top recommendations:
Invisibilia - From a former This American Life producer about the invisible forces that shape human behaviour, way more interesting than a standard podcast on psychology. Give the preview a listen
here.
No Such Thing As A Fish - Slightly irreverent podcast from the researchers for the UK TV show QI where they each talk about their favourite fact they've learned that week; anything from the salmon being more closely related to a camel than a hagfish and the way we classify species to there being more than 600 guys in the world with two dicks and discussions on gene mutations.
Strangers - From a former producer on The Moth (which I totally recommend if you've not listened to that one), these are typically just interesting stories from regular people.
You Are Not So Smart - Similar to Invisibilia, it's another interesting take on psychology with a focus on how our minds don't work the way you'd expect them to. Episode 36 on the Dunning Kruger effect (why people who can't hold a note think they're going to win American Idol) is a favourite.
Richard Herring's Leicester Square Theatre Podcast - Most of these are pretty serious so if you just need something to give you a laugh this one never fails me.
