No, not trolling.
Intelligence is largely genetically inherited. Numerous studies shows.

Are you sure you're not trolling?
And now youre moving the goal posts. Now youre saying intelligence is LARGELY inherited. In a previous post, you basically said that culture didn't matter at all, and it was ALL genetic. But, now youre saying its LARGELY genetic, implying that their may be room for other factors. Of course intelligence is very much genetic, but IT is mitigated by environmental factors.
Yes, and numerous studies also show a culture/environment of trauma affects children's brains. So, clearly, culture/environment is going to have some influence on IQ. There are articles that show the relationship between environment/culture and IQ development between children who have experienced trauma and those who have not. But, yes, you are correct, culture and/or environment means absolutely nothing lol.
Hippocampus: Adults who were maltreated may have reduced volume in the hippocampus, which is central to learning and memory (McCrory, De Brito, &
Viding, 2010; Wilson, Hansen, & Li, 2011). Toxic stress also can reduce the hippocampus’s capacity to bring cortisol levels back to normal after a stressful event has occurred (Shonkoff, 2012).
Corpus callosum: Maltreated children and adolescents tend to have decreased volume in the corpus callosum, which is the largest white matter
structure in the brain and is responsible for interhemispheric communication and other processes (e.g., arousal, emotion, higher cognitive abilities) (McCrory,
De Brito, & Viding, 2010; Wilson, Hansen, & Li, 2011).
Cerebellum: Maltreated children and adolescents tend to have decreased volume in the cerebellum, which helps coordinate motor behavior and executive
functioning (McCrory, De Brito, & Viding, 2010).
Prefrontal cortex: Some studies on adolescents and adults who were severely neglected as children indicate they have a smaller prefrontal cortex, which is
critical to behavior, cognition, and emotion regulation (National Scientific Council on the Developing Child, 2012), but other studies show no differences (McCrory, De Brito, & Viding, 2010). Physically abused children also may have reduced volume in the orbitofrontal cortex, a part of the prefrontal cortex that is central to emotion and social regulation (Hanson et al., 2010).
Other: Children who experienced severe neglect early in life while in institutional settings often have decreased electrical activity in their brains, decreased
brain metabolism, and poorer connections between areas of the brain that are key to integrating complex information (National Scientific Council on the
Developing Child, 2012). These children also may continue to have abnormal patterns of adrenaline activity years after being adopted from institutional
settings. Additionally, malnutrition, a form of neglect, can impair both brain development (e.g., slowing the growth of neurons, axons, and synapses) and function (e.g., neurotransmitter syntheses, the maintenance of brain tissue) (Prado & Dewey, 2012).
Leading expert in the field:
THE EFFECTS OF EARLY RELATIONAL TRAUMA ON RIGHT BRAIN DEVELOPMENT, AFFECT REGULATION, AND INFANT MENTAL HEALTH
ABSTRACT: A primary interest of the field of infant mental health is in the early conditions that place
infants at riskfor less than optimal development. The fundamental problem of what constitutes normal
and abnormal development is now a focus of developmental psychology, infant psychiatry, and developmental
neuroscience. In the second part of this sequential work, I present interdisciplinary data to more
deeply forge the theoretical links between severe attachment failures, impairments of the early development
of the right brain’s stress coping systems, and maladaptive infant mental health. In the following,
I offer thoughts on the negative impact of traumatic attachments on brain development and infant mental
health, the neurobiology of infant trauma, the neuropsychology of a disorganized/disoriented attachment
pattern associated with abuse and neglect, trauma-induced impairments of a regulatory system in the
orbitofrontal cortex, the links between orbitofrontal dysfunction and a predisposition to posttraumatic
stress disorders, the neurobiology of the dissociative defense, the etiology of dissociation and body–mind
psychopathology, the effects of early relational trauma on enduring right hemispheric function, and some
implications for models of early intervention. These findings suggest direct connections between traumatic
attachment, inefficient right brain regulatory functions, and both maladaptive infant and adult mental
health.
