A "dog whistle" in politics refers to a subtle message or signal that conveys a specific meaning to a targeted audience while remaining ambiguous to the general public. This technique allows politicians to communicate controversial or divisive ideas without overtly stating them, thus avoiding backlash. The term originates from the idea that a dog whistle emits a sound only dogs can hear, while humans cannot detect it. Politicians often use dog whistles to rally support from particular groups, such as racial minorities, religious communities, or political factions. By employing coded language or references, they can appeal to these groups' values or concerns without alienating broader audiences. This strategy can be effective in shaping public opinion and mobilizing voters.
