The Archer’s Paradox describes the apparent paradox that, when released, an arrow initially bends and “wraps” around the bow even though it seems to be aimed straight at the target.
When the string is released, the arrow is accelerated very quickly and begins to flex sideways. This bending motion allows the arrow to pass around the bow window or riser before it stabilizes in flight.
The correct spine value (the arrow’s stiffness) is crucial. If the arrow is too weak or too stiff, it will not fly cleanly and the point of impact will change.
In short: The arrow does not simply leave the bow in a straight line – it flexes around the bow and only then stabilizes in flight. This interaction is what is known as the Archer’s Paradox.
