The April Effect

The April Effect: Why Your Satisfaction Scores Are About to Dip (And Why It's Not Your Fault)

It's April 1st, and if you lead patient experience, employee engagement, or any function measured by human satisfaction — your scores are likely sliding. They'll bottom out this month, recover through summer, and dip again (less severely) in fall.

This isn't about your service recovery. It's not about staffing. It's biology.

Years ago, a reporter called me at NYU Langone asking if I was worried about summer satisfaction dips from new residents. I couldn't answer — and that question launched a research journey I'm still on. What I found: the dip isn't summer. It's spring. And it's not residents. It's neurochemistry.

Press Ganey confirmed the pattern across thousands of hospitals. I've since validated it in systems across the US and Middle East. Then I found it in the Google Misery Index — consumer search volumes for sadness, depression, anxiety, and stress peak in the same window. Then employee engagement data. Then financial markets. Then legal decisions. Then movie sentiment.

The pattern is everywhere humans rate their experience of anything.

The mechanism? Serotonin transporter binding follows a seasonal cycle — it peaks in spring, creating a window of neurochemical vulnerability that affects how we perceive and report satisfaction. April isn't when care gets worse. It's when our ability to feel satisfied gets harder.

What this means for you:

Your patients need more warmth right now — not because something's broken, but because their biology is working against contentment. Your staff shouldn't carry the burden of "failing" a score that's fighting physics.

It matters if you're running a hospital, physician practice, building an app or measuring anything humans rate.

How does your data look? Is your dip over or just beginning?
