We remember the answered prayers and forget the unanswered ones. This is not evidence of God. It is evidence of how human memory works.
You pray to find your lost keys. An hour later, you find them under the couch cushion. "Thank you, God!" you exclaim.
But what about the hundreds of times you prayed and the keys stayed lost? What about the times you prayed for a sick relative who died anyway? What about the test you prayed to pass but failed?
Those do not count, do they? That is confirmation bias, and it is the engine that drives belief in prayer's effectiveness.
What is Confirmation Bias?
Confirmation bias is our tendency to:
Notice and remember information that confirms our existing beliefs
Ignore, forget, or rationalize information that contradicts our beliefs
This is not a moral failing. It is how human brains are wired. We are pattern-seeking creatures who evolved to find connections, even when none exist.
How It Works with Prayer
Here is the pattern:
When Prayer "Works"
We prayed and the desired outcome occurred
We attribute causation: prayer caused the outcome
We remember this vividly and share it as testimony
When Prayer "Fails"
We prayed and the desired outcome did not occur
We rationalize: "God has a different plan," "It was not meant to be," "God said no"
We forget this or do not count it as data
This creates an unfalsifiable belief system. Prayer gets credit for successes and is excused for failures. No outcome can ever count as evidence against prayer's effectiveness.
The Texas Sharpshooter Fallacy
This is related to another fallacy: the Texas Sharpshooter. Imagine a shooter who fires randomly at a barn, then paints a bullseye around the tightest cluster of bullet holes. It looks like precision shooting, but it is actually random chance with after-the-fact interpretation.
Prayer works the same way. We shoot prayers at random outcomes, then paint bullseyes around the "hits" while ignoring the scattered misses.
If you genuinely want to know whether prayer works, you need to track it objectively. Here is a simple template:
| Date | Prayer Request | Specific Outcome Requested | Deadline | Actual Outcome | Match? |
|------|----------------|---------------------------|----------|----------------|--------|
| Jan 1 | Healing for Mom | Cancer remission within 6 months | July 1 | [Record result] | Yes/No |
| Jan 5 | Job interview | Get the job offer | Jan 20 | [Record result] | Yes/No |
Rules for the audit:
Be specific about what you are asking for
Set a deadline for evaluation
Record the outcome honestly
Do not retroactively reinterpret the request
Calculate your success rate after 50 or more entries
If prayer works better than chance, your success rate should be significantly above what random chance would predict. Spoiler: studies that have done this rigorously find no effect.
The STEP Study
In 2006, the Study of the Therapeutic Effects of Intercessory Prayer (STEP) was published. It was the largest scientific study of prayer ever conducted:
1,802 cardiac bypass patients
Three groups: prayed for and told, prayed for and not told, not prayed for
Result: No difference in outcomes between groups
Patients who knew they were being prayed for actually had slightly more complications (possibly due to performance anxiety)
When rigorously tested, intercessory prayer performs no better than chance.
The Bottom Line
Prayer feels effective because we count the hits and ignore the misses. This is not divine intervention. It is a well-documented cognitive bias that affects all humans. If you want to know whether prayer actually works, you must track it systematically and honestly. When we do, the magic disappears.
