Taking Emotionless makes it so your population remains "Happy" at all times. Presence of enemy ships or losses in wars won't make your happiness level drop down; thus keeping your planets building and those ships pumping out.
But it isn't worth the 3000 points to take it. You can easily keep the population happy by building Police Troops on all your planets.
To find out more about Troops look at the Newbie FAQ stickyfied at the top of the forum; it also handles just about everything you can think of.
Oh, and welcome to the forums! You ask a question and it will be answered usually withen 20 minutes.
Edit: I took the liberty to look this up for you in the FAQ. It will tell you how you can keep your planets happy and free of Riots. (Which is basically what Emotionless does.)
12.1 Riots & Riot Control
12.1.1 The following things can increase happiness on a planet: ships in the system, ships in the sector, urban pacification centers, troops on the planet, winning a battle, colonizing a planet, capturing an enemy planet, (sometimes) new treaties, building ships or facilities.
12.1.2 Since the number of troops matters for happiness, not the strength, someone suggested making small troops with just a cockpit to use for use as “riot police.”
12.1.3 A homeworld will never riot.
Their anger will go up but it maxes out at 80% (where 100% is required to riot
But, if the HW is glassed, then recolonized, it can then be capable of rioting, as it is no longer a HW. (Slick, Imperator Fyron, Aaron)
