Leaving aside the impact on other species, charisma does not seem to protect even charismatic species against extinction. All ten of the most charismatic groups[lower-alpha 1] of animal identified in a 2018 study, namely tiger, lion, elephant, giraffe, leopard, panda, cheetah, polar bear, wolf, and gorilla, are currently endangered; only the giant panda shows a demographic growth from an extremely small population. The researchers suggest that the widespread use of images of these animals has given the public the impression that the animals are abundant, obscuring their high risk of imminent extinction.
