We will spend months stressing about a job or a start-up, which might affect our lives for the subsequent year or two or three, and no more than a few hours here and there really digging into what evidence exists to support an atheist or religious perspective. It's a cycle that sadly continues - 200 years ago everyone was Christian so people defaulted to it. Now, the trendy thing for "intellectuals" is atheism, and so many jump in without a thought (this continues to hold for both sides, as exemplified in the article).
When deciding which direction to take with a start-up we do hours and hours of customer interviews, site visits, market research, brainstorming, reading, and even self-reflection. The same, and more, should be done for religion (e.g., check out a church, speak in a truly unbiased fashion with ardent believers and non-believers alike, grab 20 minutes of a pastors time who has probably dedicated his life to talking to people like us, etc).
There is no topic that gets less thought relative to its importance.
