«كُتْرِ الضَّرْبْ يِعَلِّمِ الْبَلَادَهْ»

When someone is hit or punished over and over, the punishment loses its sting. The person grows accustomed to it, so blows that once frightened or corrected now produce only numbed, thick-skinned indifference. The dullness meant is this unresponsiveness, not low intelligence.

More broadly, the saying faults excessive punishment as self-defeating. Constant reproach or penalty trains its target to stop caring, leaving the one who disciplines with less influence than before. It criticizes the excess and should not be read as approving of moderate beating.

Suitable when someone complains that relentless scolding, penalties or physical discipline have stopped working on a child, worker or anyone repeatedly reprimanded. It cautions that piling on more of the same only deepens indifference; it does not endorse beating in moderation.
