    "headline": "Study Links Tongue-Folding Ability to Cognitive Skills",
    "dek": "Research finds a correlation between the ability to fold the tongue into a U-shape and higher scores in creativity and problem-solving tests.",
    "prose": "A study published in ScienceDirect analyzed 1,066 students to investigate relationships between tongue flexibility and cognitive abilities. [^1]\n\nResearchers found that students with the highest scores in creativity and complex problem-solving tests more frequently possessed the ability to fold their tongues into a U-shape. [^2]\n\nAccording to Gardner's theory, there are nine distinct types of intelligence: naturalistic, musical, logical-mathematical, existential, interpersonal, bodily-kinesthetic, linguistic, intrapersonal, and spatial. [^3]\n\nHoward Gardner, an American psychologist and education researcher, developed the theory of multiple intelligences, which holds that people have multiple distinct abilities rather than a single intelligence. [^4]\n\nResearchers stated that the ability to fold the tongue is not a definitive proof of intelligence, but rather an observed association. [^5]\n\nThe study identified that 122 students with the highest evaluation scores were able to perform the tongue-folding movement. [^6]\n\nGardner described existential intelligence as the intelligence of 'big questions' about human existence, but he himself did not consider it fully proven as a separate intelligence type. [^7]\n\nThe article concludes that intelligence should not be identified with a single number or ability, since different people can excel in different areas and intelligences combine. [^8]",
