Passage Summary: Typing causes carpal tunnel, but a study found that office workers who have very little say over their work are much more likely to get the condition than workers who do the same amount of typing but have more control.

Reasoning: Carpal tunnel is linked to repetitive motion, yet workers with less control over their tasks have three times the risk of developing the syndrome compared to those with more control, despite doing similar amounts of typing.

Analysis: This paradox presents a physical cause for a condition but then introduces a social or psychological variable that significantly changes the outcome. To resolve this, we need to find a link between 'lack of control' and 'physical injury.' Perhaps workers with less control are under more stress, which causes muscle tension, or perhaps they are less likely to take the small, frequent breaks that those with more autonomy might take. Look for an answer that explains how the psychological state of 'control' manifests as a physical benefit or risk.
