On March 21, 1846, a post office was established at the intersection of present-day highways KY 640 and US 68/KY 80. The community was named Randolph, in honor of John Randolph, U.S. Senator and Congressman from Virginia. Edward V. Cummins served as the first postmaster. The community began declining in the 1860s, with businesses closing. In 1873 the post office closed as well. Residents of a newly forming community 2.5 miles south petitioned to have the post office relocated there and on August 12, 1873, it was opened, with the name Randolph moving to the new community.

In 1890, G.S. Neville built and began operating a store at the old Randolph site and a new community began to spring up. Around 1894, Em Evans took over the operation of the store and petitioned for a new post office to be established. The name Wisdom was submitted, in honor of Silas Henry Wisdom (1849–1898), first Superintendent of Schools for Metcalfe County. The post office was approved and Wisdom officially became a community.

Wisdom's main industry remains agriculture, with several large scale farming operations located within or nearby the community. Beef and dairy cattle are both raised, as well as poultry. The most prevalent crops are tobacco, corn, soybeans, hay and forage.

Residents who are employed outside of agriculture typically work in either Edmonton or Glasgow.

The only current public business in Wisdom is Gilley Shooting Supply, located approximately 0.2 miles south of the community center. Hunley's Grocery and Mosby's Used Cars are approximately 1.5 miles west of the community center.

Wisdom is the home to three active church congregations:

• Wisdom Cumberland Presbyterian Church
• Wisdom Faith Community Church

Dripping Springs Baptist Church is one of the oldest churches in the region. The church was constituted February 3, 1798 while it was still part of Barren County - now Metcalfe County. It was originally located about midway between Glasgow and Edmonton. It was first known as the Sinks of Beaver Creek Baptist Church until Sept of that year. The name was changed to Dripping Springs supposedly because of the location for the church building being near a large rock that had a dripping spring.

The first church was built about 1800, a log structure, and was 1+1⁄2 stories tall. There was a gallery above with seats for the men if the lower section was full. In the summer of 1874, a new church building was erected that was 2 stories tall. In 1890 another church was built and in 1961 the current building.

The Wisdom Homemakers remain an active and vital part of the community.

Wisdom is a favorite stop for many during the 400-Mile Sale, which takes place along U.S. Highway 68 during the first weekend of June. The event features yard sales from Paris, Tennessee to Maysville, Kentucky.

Dripping Springs Baptist Church is the site of a Kentucky Historical Marker. The text of the marker reads, "Organized as Baptist 'Sinks of Beaver Creek,' 1798, at William Blakely home. Services continuous since first building about 1799, log cabin. In 1874, hand dressed yellow poplar structure replaced original. Present building erected in 1961. Name changed, but same organization continued. Over the years members have withdrawn to form other churches in the area."

Kentucky Highway 640, which crosses U.S. Highway 68 in Wisdom, is officially known as Kentucky Headhunters Band Highway. The designation was part of a bill sponsored by State Representative Bart Rowland (R-Tompkinsville) during the 2013 Kentucky General Assembly.
