Luckily, you can develop the confidence of a serial killer without sacrificing any of your moral standards.

If you want someone to rally to your cause, support your position or put you in a position of authority, you need to be able to back up your positions and sway others from theirs. The trouble is not every point has supporting data, and not every opinion is swayed by facts. That doesn't have to slow you down though. Here's how to find data to support any point, even the ones you disagree with, so you can better inform your own.

OK, if you don't think our Evil Week suggestions so far have been nasty enough, or you just don't like the increasing prominence of Halloween in Australia, this will appeal.

We all have that one friend who is ridiculously prickly when it comes to movie spoilers. You know the type we're talking about -- the moment anyone brings up a movie they haven't seen, they fly into an indignant, teeth-gnashing rage.

Even if the "spoiler" is insignificant to the plot, they'll still relentlessly guilt-trip you and try to make you feel like a thoughtless monster. We think this behaviour needs to be stamped out. With extreme prejudice.
