All have the potential of making you smarter. Add to that the way you pray and the recipient of your prayers.
At least in terms of college education, religion seems to be a factor in the attainment of a degree.
That's according to a new study by the Pew Research Center that looks at the attainment of a four-year college degree in the United States according to religious affiliation.
The largest share of educated adherents? Hindus. Nearly 80 percent of Hindus in this country have a college degree. (The majority of Hindus come from India).
Following closely are the members of the Unitarian Universalist faith tradition with a 67-percent rate of college attainment. Immediately after them come the Jewish and Anglican faiths with 59 percent each.
Noting the strong correlation between educational attainment and economic success, the Pew study notes that Jews and Hindus, on average, have high household incomes, with four-in-10 Jews (44 percent) and roughly a third of Hindus (36 percent) living in households with annual incomes of at least $100,000, according to the 2014 study.
The numbers come out of the 2014 Religious Landscape Study, which surveyed a full sample of more than 35,000 U.S. adults.
Other religious groups that have a higher percentage of college graduates than the full sample (at a 27 percent rate) include:
Buddhists and members of the Presbyterian Church (U.S.A.) - both at 47 percent
Orthodox Christians: 40 percent
Muslims: 39 percent
Mormons: 33 percent
Catholics make up one-in-five adults, a fact reflected in their share of 26 percent attainment - roughly mirroring that of the general public.
Among the historically black Protestant denominations, the rates reported were:
The National Baptist Convention: 19 percent
The African Methodist Episcopal Church: 21 percent
Southern Baptist Convention: 19 percent
The lowest rates of college education attainment was seen in:
Church of God (Cleveland, Tenn.): 11 percent
American Baptist Churches USA: 12 percent
Jehovah's Witness: 12 percent
Church of God in Christ: 13 percent
Assemblies of God: 15 percent
Non-believers were also plugged into the findings. The Pew study found these rates of educational attainment among religiously unaffiliated people:
Atheists: 43 percent
Agnostics: 42 percent
Those reporting that their religion is "nothing in particular": 24 percent
