I'd date the Beautiful and dumb but I'd give a job to the intelligent one. Why? Well the job one is obvious but the dating ones a little trickier. I've dated girls as smart as me and smarter than me. It doesn't really make things that much better. I mean I love talking science and it's cool when you already somewhat understand what I'm talking about but like 95% of my relationship life is filled with really simple things like Netflix and eating and sex. Knowing quantum doesn't make you a better cuddled. I've got friends to talk academic stuff with. I've also dated people who were insanely attractive and those who weren't very attractive at all and it did make a huge difference. I rarely got excited to spend time with a girl cause she was so smart. Being smart just kind of felt like a cool bonus. But those few extremely beautiful girls that I've dated are burned into my memory as being some of the most fun I'd ever had in relationship. So I kind of feel like if you asked a kid which stuffed animal they want the super soft teddy bear or the fury that can talk. The curvy at first seems like the cooler toy but eventually it's going to just get annoying. The soft teddy bear is going to be a lot more appealing for a lot longer. Sorry if that makes me sound shallow but you asked for honesty.
Really it should not be so difficult to have both. But anyway, beauty implies aesthetics, and is actually quite rare, so I'll go with that. But beauty would also imply a certain level of intelligence, so, I'm not concerned about selecting beauty. I'm sceptical about the so called air headedness of this beautiful person :)
Intelligence!! That's a no brainer for me. I would much rather have a relationship with someone who I could have intellectual conversations with than someone who knows nothing. Plus, I think relationships are more about the romantic attraction than the sexual.
