Have you ever considered buying a DNA kit for a family member as a special gift, such as Father’s Day? On the surface, it may seem like a good idea, as it allows loved ones or friends to peer into their past and family history; however, psychologists have recently warned against it, as it might have profound psychological implications.
In a new book titled The Psychology of Genealogy, Dr. Susan Moore, a retired Australian university researcher in social and developmental psychology, examines the complex emotions associated with DNA testing and uses real-life case studies to illustrate its psychological impact.
“Should you give DNA kits as gifts? It can be fun, [but] it can be risky,” Moore says in a statement.
Moore cautions that the psychological impact of DNA testing may be far greater than many people anticipate. These tests can reveal unexpected family secrets, uncover cases of misattributed paternity, disclose donor conception, and even link individuals to hundreds of previously unknown half-siblings or relatives they may not want to be connected with.
“Do first think carefully about how your intended recipient might cope with unexpected outcomes,” Moore says.
“Hobbyist family historians are uncovering joyful and inspiring stories of the past as well as sad and unsettling secrets of their ancestry,” Moore explains. “Records and DNA matches provide boosts, challenges, and even threats to one’s sense of self, and this is occurring at unprecedented levels.”
Unexpected DNA results can deeply impact a person’s sense of self and identity, along with family belonging and dynamics—a phenomenon psychologists call “identity disruption.” Moore’s book highlights cases involving revelations of misattributed parentage, late-discovered adoption, and donor conception uncovered through genetic testing, all of which caused more physical harm than good.
“At the personal level, these may be findings that cause you great distress, that destabilize your sense of who you are, that initially at least, you would have preferred not to know. Once known, however, they cannot be unknown,” says Moore.
DNA testing has also raised privacy concerns in recent years. A 2023 23andMe data breach exposed millions of users’ genetic information, while financial challenges that DNA companies have faced raise questions about what happens to genetic data if these companies fail.
Surprising statistics show that, presently, over 30 million people have tested their DNA through genealogical services like 23andMe and AncestryDNA.
Still, for many people, even with data breaches and larger companies buying up DNA data sets, it’s still enticing to buy, as their curiosity seems to outweigh the risks.
“How exciting it can be to discover the identity of an ancestor, solve a family mystery, prove or disprove family ‘legends’ or discover previously unknown living relatives,” Moore says.
“Indeed, genealogists regularly report elation and joy as they unearth lost relatives, discover the identity of a ‘missing’ ancestor, or otherwise break down ‘brick walls’ (genealogical puzzles that seem to resist solutions due to missing, inaccurate, or hard-to-access records).”
“Curiosity is a great motivator,” Moore adds.
