Why Alignment Sticks Lie to Cross-Dominant Golfers

Alignment sticks are a staple of golf practice for good reason — laid on the ground, they give an unambiguous physical reference for stance and clubface direction that's hard to argue with. The trouble isn't the stick itself. It's the assumption baked into how most golfers use it.

The Assumption

Standard alignment stick drills assume the golfer's eyes, once positioned correctly relative to the stick, will perceive that alignment as "square" consistently going forward. That assumption holds up reasonably well for a golfer whose dominant eye sits close to directly over the ball. It holds up far less well for a cross-dominant golfer — someone whose dominant eye and dominant hand are on opposite sides — whose natural eye-line often runs meaningfully off-center.

What Actually Happens

A cross-dominant golfer can lay the stick down correctly, set up against it repeatedly, and genuinely train a consistent motion — but if their natural eye-line reads that "correct" setup as slightly open or closed, they're training a repeatable swing toward a target their eyes never agreed with in the first place. The stick isn't lying about geometry; it's just not accounting for how that geometry is being perceived.

Repetition builds consistency, but it doesn't correct a perceptual bias — it can just make the biased version feel more natural over time.

How to Check If This Applies to You

Run the triangle test for dominant eye first. If you're cross-dominant, lay down an alignment stick as you normally would, then have someone check your eye-line from directly overhead while you're set up against it. A meaningful gap between where the stick says you're aimed and where your eyes are actually positioned is worth addressing before logging more practice reps against that same setup.

The Takeaway

Alignment sticks are still a useful tool, but they measure geometry, not perception. For a cross-dominant golfer especially, it's worth confirming the two actually agree before building a practice routine around the assumption that they do.
