راسل من کمی جستجو کردم و چند مقاله‌ی مرتبط پیدا کردم. نخست به تحقیق جالبی برخوردم درباره‌ی کشف ژنی که محرک خشم و خشونت در زنان است: 'Angry Gene' Could Help Spur Hostility
یکی دیگر هست که بر طبق آن اشخاصی که خشم خود را فرومی‌خورند، احتمال بسیار بالاتری برای ابراز رفتار خشونت‌آمیز به هنگام مستی دارند: People who suppress anger are more likely to become violent when drunk
و یک تحقیق جالبتر درباره‌ی گستره‌ی خشم در گروه‌های مختلف اجتماعی:

نقل قول:Younger people experience more frequent anger than older adults. This is mainly due to the fact that younger people are more likely to feel time pressures, economic hardship, and interpersonal conflict in the workplace (three core stressors that elevate anger levels);
Feeling rushed for time is the strongest predictor of anger, especially the "low-grade" forms like feeling annoyed;
Having children in the household is associated with angry feelings and behaviour (i.e., yelling) and these patterns are stronger among women compared to men;
Compared to people with fewer years of education, the well-educated are less likely to experience anger, and when they do, they are more likely to act proactively (e.g., trying to change the situation or talking it over);
Individuals who experience more financial strain tend to report higher levels of anger. This relationship is much stronger among women and younger adults.

Mad as hell? New discoveries about the experience of anger

یک مقاله هم پیدا کردم که در کمال شگفتی ادعای مهربد مبنی بر تجمع خشم و تصور مشترک و مخالف من و شما را رد می‌کند:

نقل قول:The authors experimentally examined the effects of anger suppression on pain perception. On the basis of ironic process theory, they proposed that efforts to suppress experiential or expressive components of anger may paradoxically enhance cognitive accessibility of anger-related thoughts and feelings, thereby contaminating perception of succeeding pain in an anger congruent manner

قیمت آن کمی گران (12 دلار) است اگرنه آنرا می‌خریدم.
یک نگاهی بیاندازید، نظرتان چیست؟ دوستان نیز همینطور.
نوبت به روانشناسی که می‌رسد تئوریها و آزمایشات آنقدر متناقض هستند که آدمی متحیر می‌ماند.. وانگهی این تحقیقات و مطالعات دستکم بهتر از نظریه پردازی تنهاست.
