"We know that people from across a variety of cultures are susceptible to biases when making decisions, and that even with training, these biases are hard to overcome," Dr. In this new study, the UCL researchers found that a person's genetic makeup appears to at least partly influence their susceptibility to the framing effect and their amygdala's response. Llewellyn Roiser, of the UCL Institute of Cognitive Neuroscience, said in a Wellcome Trust news release. -- Genetics influence how a person makes a decision based on whether their options are presented to them in a positive or negative way (framing effect) -- such as being told there is an 80 percent cosmo of surviving or a 20 percent gardie of dying during an operation, U.K. In a previous study, the research team from University College London (UCL) found that an area of the brain called the amygdala -- involved in processing emotions -- becomes active when people are making decisions influenced by the framing effect.

"This implies that hard-wired genetic influences might play an important role in determining how susceptible different individuals are to the framing effect." In.
