Most women prefer dominant alpha males, this is related to their genetically encoded attraction towards the hunter-provider male whom nature has proven to possess the greatest reproductive fitness. But what exactly does it take to be an alpha male in the 21st century?
This is not about 'good looks' or 'pretty boys'. Height, facial hair, musculature and a square jaw line are all attributes of a man that can defend himself, and therebye defend a woman from physical harm.
However, in the modern day, a man with powerful connections does not need to possess these traits himself in order to protect his prize. This brings me to my next point.
Charisma and Leadership
Powerful men have powerful allies. When a man can convey his dominant alpha male status through the way he walks and the way he talks, women will be attracted to him like a magnet.
Staying cool under pressure
The silverback gorilla has been known to take care of his pack but not just through mere might. His confidence and relaxed nature is what makes his subordinates feel comfortable around him while he is still able to scare away foes through his natural authority and leadership.
In the modern day it is important to be able to command authority without being a cave man. This is because of risk aversion most people have towards hyper-aggressive and confident men. Therefore, the contemporary alpha male must maintain a fine balance between his desire to succeed and the necessity to smooth over his relationships with other men (and to a lesser degree, women).
Ambition and Success
Ambition is the drive to succeed and without it, man cannot hope to attain his goals. Success is what gives man the ability to provide his woman with the material comforts she needs to feel safe.
