Expert writing Tips
Best practice
When discussing cognitive processes, use "mental effort is" to emphasize the exertion of mental energy, particularly when contrasting it with physical effort or automated processes. For example, "While physical labor might seem tiring, the "mental effort is" often underestimated".
Common error
Avoid using "mental effort is" interchangeably with "mental ability". Effort refers to the energy exerted, while ability refers to one's capacity. For instance, instead of saying "High "mental effort is" a substitute for ability", clarify that effort can compensate for, but not replace, inherent ability.
