Red pill, to some degree, celebrates aggression and anger and claims it's a male quality that the feminized world is suppressing unfairly (implying behaving in a civilized manner is feminine and being hostile is masculine). But looking at the research (see below) aggression seems to be a somewhat non gender specific trait (in fact one study below found women were more aggressive) which is correlated to emotional instability (in many ways the opposite of stoicism), depression, low accommodation (selfishness), low grades, violence, peer rejection, substance abuse, among other things. If you have issues with anger and aggression, instead of blaming the world for not accepting them and/or causing them, you should be looking for help, working on dealing with what are actually indicators of organic mental/physical health issues that will significantly lower your quality of life if not improved/fixed.

See the research below to get a better understanding of the meaning, consequences, and implications of aggression and anger. Post your own studies if you think aggression and anger are not represented fairly by the research listed below.

Results indicated neuroticism and, to a lesser extent, (low) agreeableness, were the traits most associated with components of trait anger. Conscientiousness and extraversion were also noted to show links to more focal components of anger.

As expected, neuroticism was a powerful predictor of all outcome variables and agreeableness was a significant inverse predictor of Anger-Out (AX/Out), aggression, and Trait Anger (T-Ang). Consistent with our second hypothesis, conscientiousness was a significant predictor of Anger Control (AX/C), as well as AX/Out, aggression, and T-Ang.

In summary, we found Big Five personality traits to be signifi- cant predictors of anger expression and also of trait aggression. High neuroticism and low agreeableness were both linked with enhanced expressions of anger and aggression, alongside a role for conscientiousness on anger control and for (low) extraversion on inwardly-expressed anger.

While the observed associations between neuroticism and anger expressions cohere with previous work (Martin et al., 1999), the link between neuroticism and aggression was more unexpected. Indeed, several of neuroticism’s facets (i.e., anxiety, self-consciousness, vulnerability) seem intuitively opposed to the potential risks (e.g., physical assault) associated with confronting another individual. This result may reflect the nature of the MPQ aggression measure, with three of the four items tapping a more reactive form of aggression (e.g., ‘‘When people insult me, I try to get even’’), which more closely coheres with the tendency of the neurotic individual to react more strongly to negative events.

For physical aggression, results showed that Agreeableness was indirectly negatively related to aggressive behavior via both aggressive emotions and aggressive attitudes. Neuroticism was indirectly related to aggressive behavior through aggressive emotions.

Within the context of the learning processes in GAM, this suggests that the personality dispositions of individuals will be related to developing an aggressive personality depending on the specific Big 5 trait. For instance, when confronted with a hostile situation (e.g., a provocation), disagreeable individuals are more likely to notice, attend to, and process antisocial or hostile cues, increasing the likelihood of hostile attributions, and interactions, and thereby reinforcing a range of aggressive schema and scripts.

Research has shown that aggressive behaviors contribute significantly to school failure, delinquency, peer rejection and substance abuse (Pope & Bierman, 1999; Kupersmidt & Coie, 1990; and Loeber, 1990).

Pope and Bierman (1999) stated that childhood aggression is one of the most stable, and prevalent behavior problems in childhood. They assert that aggression is related to peer rejection, and is a predictor of delinquency, school failure and substance abuse. Other researchers have supported these findings (Kupersmidt & Coie, 1990; Loeber, 1990). Additionally, research suggests that children who exhibit aggressive behaviors are at greater risk of developing future problems when they are rejected by their peers (Bierman & Wargo, 1995; Pope & Bierman, 1999), Some of the characteristics that cause children to become rejected by their peers may include increased hyperactivity, inattentiveness and immature behaviors in addition to the aggressive behaviors. These behaviors may also contribute to the same children's inability to focus in school, thus the relationship with poor academic performance (Pope & Biernlan, 1999). Students who are ostracized by their peers in school may form alliances with other children who share the same deviant interests (Pope & Bierman, 1999~ Cairns et aI., 1989; Dishion, Andrews, & Crosby, 1995).

Grade point average was significantly different for males and females. Aggression was highest in female students. Each of the Big Five personality variables, as measured by the Adolescent Personal Style Inventory (APSI), was significantly correlated with GPA. The correlation between the APSI Aggression scale and GPA was -.37, which was higher than any of the Big Five personality variables. Aggression was significantly correlated with both male and female GPA, although the relationship with female GPA was significantly higher than for males.

Agreeableness relates negatively with aggressive driving, as shown by other studies (Dahlen et. All, 2011, Benfield et.all, 2006) as well as with all the 5 factors of aggressive driving behavior. There are also negative relations between conscientiousness and each of the following terms: aggressive behavior, instrumental aggression, anger and enjoyment of violence

Previous research has shown that men behave more aggressively in traffic than women (Vamlaar, Simpsoms, Mayhew & Robertson, 2008 Seibokaite, Endriuilatiene & Marksaityte, 20011 Britt & Garrity, 2006). The same happened in this study, observing that men adopt behaviors characteristic for enjoyment of violence, acting out and negativism more intense and more frequent than females. However, in terms of aggressive driving behavior no significant gender differences were found.

A direct significant relationship was established between neuroticism and aggression [26]. Similarly, a research by Ferguson et al. [19] displayed aggressiveness as the common trait among males with a neurotic personality, marked by worry and pessimism. Wiebe [27] found that the personality traits of agreeableness and conscientiousness in the “Big Five” were found to be predictive of criminal and aggressive behaviour.

The serotonergic disturbances found in some depressed individuals, particularly those with lowered CSF 5-HIAA, are linked to the anxiety and aggression components of the depressive syndrome. In this type of depression, called 5-HT-related depression, dysregulation of anxiety and/or aggression is hypothesized to be primordial and mood-lowering is a derivative phenomenon.

The 5-HT ergic disturbances found in some depressed individuals - and of them particularly lowered CSF 5-HIAA - are linked to the anxiety- and the aggression-components of the depressive sydrome. In this type of depression - called 5-HT related depression - dysregulation of anxiety and/or aggression are primordial and mood lowering is a derivative phenomenon. In other words this is a group of anxiety/aggression-driven depressions. The 5-HT ergic impairment in certain types of depression is a trait-phenomenon, ie, persists during remission. This disturbance makes the individual susceptable for perturbation of anxiety- and aggression-regulation. Anxiety and (overt or suppressed) anger, are core constituents of the stress-syndrome.

Depression is commonly thought of as counter-indicative of aggression because of apparent contradictions in energy requirements and blame orientation. However, empirical studies indicate that the presence of depression elevates risk for general aggression, intimate partner aggression, and self-aggression. Most of these studies are cross-sectional and retrospective, hence, there is scant empirical evidence for depression as a causal factor for aggression. However, there is considerable evidence for an association between depression and aggression. Depression as a risk marker for aggression may stem from a third factor such as genetics, personality disorder or insecure attachment. There are also a number of sequelae of depression that may contribute to this increased risk for aggression including isolation, lost social support, increased alcohol use, angry rumination, and impulsivity. Furthermore, affective swamping clouds attributional clarity so that internal and external attributions for negative feelings become fused and undifferentiated. Hence, negative events of sufficient affective impact can generate both depression and anger. One form of this affective swamping is scapegoating: finding an external person or persons to blame for “causing” aversive affect.
