In terms of the vibe of this school, also with a higher acceptance rate
If to your mind the vibe is lefty lefty and intellectual–try Oberlin and Hampshire and Bard
If to your mind the vibe is intellectual for intellectualism’s sake – try U of Chicago and Swawrthmore and Yale (harder to get into I know)
If to your mind the vibe is delight in smart ideas and fun–try Beloit
You may also want to consider
Evergreen
Marlboro
Earlham
Haverford
Vassar (if you’re male, the acceptance rate is better)
U of Rochester
Wesleyan
Some of these:

If you identify as female, also consider Bryn Mawr–it’s very intellectual too and it’s part of the consortium that includes Haverford, Swarthmore, and UPenn
You will get better answers if you can be more specific about which aspects of the Reed “vibe” that you want to duplicate.
The first names that came to my mind as “schools like Reed but with higher acceptance rates” were Lewis & Clark and the University of Puget Sound. All three schools are urban liberal arts colleges in the Pacific Northwest, and all three schools have scored highly in the past in the “Birkenstock-Wearing, Tree-Hugging, Clove Smoking Vegetarians” ranking. Of the two, L&C is closer to Reed in terms of location, size, and selectivity.
