Did Gattaca come true?
Gattaca got the instruments almost exactly right: embryos are ranked by polygenic score for paying customers, a DNA test can settle identity in about 90 minutes without a lab, and England plans to read every newborn's genome. It got the gatekeeper wrong. Genetic discrimination in hiring was outlawed before it took hold, and the sorting moved to the fertility clinic instead.

How this P(n) was calculated
Each prediction is weighted 1–5 by how pivotal it is to the story: 5 is the core premise, 1 is background detail. Arrived scores 1, arriving 0.5, everything else 0. P(n) is the weighted points divided by the total weight.
| Claim | Prediction · why this weight | Weight | Status | Value | Points |
|---|---|---|---|---|---|
| GAT-1 | Parents using IVF can choose between embryos ranked by their predicted genetic risk of common diseases. Major: Anton's selected conception against Vincent's natural one is the film's central contrast. |
4 | ARRIVED | 1 | 4 |
| GAT-2 | Employers screen job applicants' DNA and give the best jobs to the genetically favoured. Core premise: genetic discrimination at work is why Vincent must borrow Jerome's identity. |
5 | DIVERGED | 0 | 0 |
| GAT-3 | Officials can confirm who someone is from a DNA sample in about the time it takes to pass a checkpoint, without a laboratory. Supporting: constant DNA checks are the obstacle Vincent's deception must beat daily. |
3 | ARRIVED | 1 | 3 |
| GAT-4 | Every newborn's genome is read at birth and used to predict their risk of disease. Supporting: the birth readout fixes Vincent's prospects in the opening and shapes his life. |
3 | ARRIVING | 0.5 | 1.5 |
| Total | 15 | 8.5 |
P(n) = 8.5 ÷ 15 = 57% · unweighted average 62%

Polygenic embryo screening (PGT-P) is sold commercially; Orchid markets whole-genome embryo reports with risk scores for conditions such as heart disease, diabetes and schizophrenia. By December 2021 the European Society of Human Genetics reported that at least one child had been born after such selection. The science is weak: a polygenic score on an embryo predicts little, and geneticists have called the practice unproven. It has arrived as a product, not as the precise forecast the film imagined. 12

Employers screen job applicants' DNA and give the best jobs to the genetically favoured.
Weight 5/5 · Core premise: genetic discrimination at work is why Vincent must borrow Jerome's identity.
The law moved first. The US Genetic Information Nondiscrimination Act of 2008 bars employers from using genetic information in hiring, firing or promotion, and the UK insurance industry's code bars insurers from using predictive genetic test results, except Huntington's disease for life cover over £500,000. Genetic sorting has instead moved into reproduction and private testing, where no employer is involved. 34

Officials can confirm who someone is from a DNA sample in about the time it takes to pass a checkpoint, without a laboratory.
Weight 3/5 · Supporting: constant DNA checks are the obstacle Vincent's deception must beat daily.
Rapid DNA instruments produce a profile in under two hours with no human interpretation and can be run by non-specialists in the field. In 2019 US immigration authorities piloted them at the Mexican border to test whether children were biologically related to the adults with them, with results in about 90 minutes. Using them on degraded traces like a single shed eyelash at a crime scene remains harder and more restricted. 56

Every newborn's genome is read at birth and used to predict their risk of disease.
Weight 3/5 · Supporting: the birth readout fixes Vincent's prospects in the opening and shapes his life.
Genomics England's Generation Study is sequencing the genomes of 100,000 newborns to look for more than 200 rare conditions, and the government's 2025 health plan commits to universal newborn genomic testing and population-wide polygenic risk scoring. The plan sets out an ambition, not a funded rollout date, and screening for rare treatable conditions is still a long way from Gattaca's lifespan forecast. We put universal sequencing in England in the early 2030s. 78
- FOR PGT-WGS: Whole Genome Embryo Screening. Orchid. A US company sells whole-genome embryo screening including polygenic risk scores for complex conditions.
- AGAINST The use of polygenic risk scores in pre-implantation genetic testing: an unproven, unethical practice. European Journal of Human Genetics, 2021-12-17. The ESHG says PGT-P is being marketed and at least one child has been born after it, but its predictive value is severely limited and untested.
- AGAINST Genetic Information Discrimination. U.S. Equal Employment Opportunity Commission. GINA makes it illegal for employers to use genetic information in employment decisions or to request it, with narrow exceptions.
- CONTEXT Code on Genetic Testing and Insurance. Department of Health and Social Care / Association of British Insurers, 2018-10-23. UK insurers may not ask for or use predictive genetic test results, with one exception: Huntington's disease for life insurance over £500,000.
- FOR ICE's Rapid DNA Testing on Migrants at the Border Is Yet Another Iteration of Family Separation. Electronic Frontier Foundation, 2019-08-02. Describes the 2019 ICE pilot and a DHS assessment saying parentage tests take about 90 minutes without human review.
- FOR The 2018 California Wildfires: Integration of Rapid DNA to Dramatically Accelerate Victim Identification. Journal of Forensic Sciences, 2020-03-03. Rapid DNA generated profiles in under two hours without human interpretation and helped identify 58 Camp Fire victims; it studies remains, not crime-scene traces.
- FOR 10 Year Health Plan for England: fit for the future. Department of Health and Social Care, 2025-07-03. Commits to a genomics population health service with universal newborn genomic testing and population-based polygenic risk scoring.
- FOR Newborn Genomes Programme. Genomics England. The Generation Study will sequence 100,000 newborns' genomes, looking for more than 200 rare conditions.
