What scientific method is implicitly critiqued in the movie through the title GATTACA?

The title "GATTACA" refers to the nucleotide sequences that make up DNA, specifically the bases guanine (G), adenine (A), thymine (T), and cytosine (C). Within the context of the movie, it serves as a representation of the genetic engineering and manipulation prevalent in the society depicted. The film implicitly critiques eugenics—a scientific method that seeks to improve the genetic quality of the human population through selective breeding and other genetic interventions.

Eugenics has a historical connection to controversial and unethical practices aimed at controlling reproduction to promote the desired traits in humans, which often leads to significant social and moral implications, including discrimination against those deemed "genetically inferior." "GATTACA" explores these themes by showcasing a world where people's lives are predetermined by their genetic makeup, raising questions about free will, the significance of genetic identity, and the ethical boundaries of scientific advancement. The characters' struggles illustrate the consequences of a society that prioritizes genetic perfection over individuality and human potential, making it a poignant critique of eugenics as a scientific approach.
