The latest episode of 99% Invisible (an incredible podcast about design and architecture) focuses on the notion of designing for the "average" person, focusing on how the U.S. military's philosophy of crafting uniforms and equipment has evolved over the decades:
In his research measuring thousands of airmen on a set of ten critical physical dimensions, [Gilbert S.] Daniels realized that none of the pilots he measured was average on all ten dimensions. Not a single one. When he looked at just three dimensions, less than five percent were average. Daniels realized that by designing something for an average pilot, it was literally designed to fit nobody.
The result was an increased risk of injuries and fatal accidents, especially for Air Force pilots who literally didn't fit in cockpits designed for the "average" pilot.
Today, we take for granted that equipment should fit a wide range of body sizes rather than being standardized around the “average person.” From this understanding has come the science of ergonomics: the study of how to match people’s physical capacity to the needs of the job.
Unfortunately our evangelization and catechesis is, in a lot of ways, still stuck in "average" thinking. Many parish programs are designed to attract as wide an audience as possible -- that is, to be "one size fits all." A good example is taking the RCIA and inviting any interested Catholic adult to participate. What should be a highly specialized process for those still seeking faith in Christ must now be adapted to fit the needs of a wide range of the baptized, resulting in a program designed for no one in particular.
What would a parish catechetical program designed outside the average look like? I believe it would
- Center on more focused topical and needs-based formation, rather than "big box" overviews of the faith
- Include input from persons with disabilities, ethnic and racial groups, and the poor
- Seek to match people's spiritual capacity with a range of formational option
There is no "average" spirituality or faith. The saints testify to the glorious diversity of individual responses to Christ invitation to "take up your Cross and follow me." (Matthew 16:24) The faithful in our parishes should be formed for that same diversity of holiness, even as we are united in the one Body of Christ.
