Though most studies have shown that blood type doesn’t directly influence personality, some experts still believe there may be more to the story than what’s flowing through your veins. Is there any link at all between personality and blood type? Since this concept’s emergence in Japan in the late 1920s, the blood type personality theory has been the subject of many studies worldwide.Ĭurrently, no scientific evidence supports a cause-and-effect relationship between a person’s blood type and personality traits.Įven using current investigative methods, a 2021 study examining blood type and personality demonstrated no significant correlation. It was maintained and publicized by his son, Toshitaka Nomi, until Toshitaka died in 2006.

Nomi added to the original blood type personality theory and suggested that blood type could be linked to disease or physical predispositions.Īnd like Furukawa’s work, Nomi’s report also came under heavy scrutiny for being uncontrolled and anecdotal.ĭespite this criticism, his outline for blood type personality theory remains the basis for current models. He included data from multiple method approaches, such as: In his report “Understanding affinity through blood type,” Nomi expanded on Furukawa’s concepts. It was brought to the scientific community a second time in the 1970s by independent researcher and journalist Masahiko Nomi. The theory of blood type personality persisted, however. After publication, the evidence was later questioned due to possible political influences and the too-small sample size used in the research. In his research, Furukawa linked personalities to different blood types.įurukawa presented preliminary statistics for his theory based on small population samples. This process allows us to collect more red cells, which are the most critical part of an O-negative blood donation.Blood type personality theory was first introduced in 1929 when professor Tokeji Furukawa published “ A study of temperament and blood-groups.” During a double red cell donation, your blood is separated into its components during the donation process and the platelets and plasma portion are returned to you. Some donors may qualify for double red cell donations. You’re probably familiar with whole blood donation. That’s the type of donation you’ll find on most bloodmobiles.ĭuring whole blood donation, a pint of blood is taken from the donor and then later separated into its components – red blood cells, platelets, and plasma. So, yes, we want your blood donation, we need it. When someone with O-negative blood has an accident or undergoes surgery, they must receive an O- transfusion. But it is also the only blood type that can save O Negative recipients. O Negative blood can help save any and all trauma patients, premature babies, and cancer patients. In fact, O-negative blood is often used for premature infants and babies who need blood transfusions. Once doctors determine the patient’s blood type, they can switch to that type of blood.īut even then, O- blood is still an option. It is estimated that 7 percent of the population has O- blood type while only 1% of the population has AB- blood.īut because the red blood cells of O- blood donors can be transfused into patients with any blood type, it is often the first choice for transfusions necessary in trauma situations.

Myth: O Negative blood is the rarest blood typeĬontrary to popular belief, O- blood is not the rarest blood type.
