The Thinking Face Emoji (🤔) was introduced as part of Unicode 8.0 in 2015 and quickly transitioned from a simple communication icon to a versatile meme staple. Represented as a yellow face with a furrowed brow and a hand resting on its chin, it is universally used to signal skepticism, deep contemplation, or to highlight a logical fallacy. In internet culture, the emoji is often paired with ironic 'big brain' takes or used to respond to posts that seem suspicious or contradictory. Its popularity surged during the 'thinking emoji' boom of 2016-2017, leading to various spin-offs, including rotating, distorted, and 3D versions that amplify its sarcastic and questioning undertones.
