Can we offset genetic biases?

Sources:

has discussed the concept of offsetting genetic biases in the context of different predispositions.

  1. Genetic Predisposition to Aggression:

    • Environmental factors can significantly modulate genetic predispositions. For instance, genetic variants affecting estrogen receptor sensitivity can influence aggression levels, but this can vary depending on the length of day and night. Proper sunlight exposure can mitigate this effect by regulating cortisol levels and reducing aggressiveness 1.

  2. Inherited Trauma:

    • Research indicates that trauma or a predisposition to fear can be inherited across generations. This doesn't mean descendants will necessarily experience the same trauma, but they might have a lower threshold for developing fear responses due to genetic changes in their ancestors. Awareness and environmental modifications, such as managing stress and exposure to nurturing conditions, can help offset these inherited predispositions 2.

These insights highlight that while genetic predispositions exist, environmental factors and conscious interventions can help mitigate their effects.

Genetic Aggression

Andrew discusses the genetic predisposition to aggression and how it is influenced by day length. He explains how genes generally code for things within our biology and how they bias our biology. Andrew also emphasizes the importance of paying attention to how we feel at different times of the year and taking steps to offset genetic biases.
