How I Judge
I am receptive to most kinds of arguments, but this post captures my judging philosophy well: http://trolleyproblem.blogspot.in/2012/11/what-does-good-judge-believe.html. tl;dr: I like hearing novel and interesting arguments, but I have "a defeasible presumption in favour of a moderate liberal position on most ethical issues... By "defeasible", I mean that the presumption could in principle be overcome by a persuasive argument, [and if so, I will listen to such] arguments with an open mind." I love weighing, and I don't think your argument being dropped (however coldly so) constitutes a winning weight.
My speaks reflect the quality of warranting and impacting-weighing. But, just saying "scope, clarity, and probability" isn't enough. Spend time on weighing and do interesting weighing on actor or scope or principle or whatever else. I don't care for rhetoric or style.
I also hold the belief that human extinction is unlikely.
Warranting vs Evidence
I always prefer better-explained mechanisms and logical warrants over evidence. I care about evidence only when a claim isn't intuitive to believe just based on warrants. Do use evidence to make counter-intuitive warrants/claims stronger but don't use it when it doesn't contribute to the believability or power of your logic.
Choose your evidence well: suss sources are just that—suss.
Line-by-line is good but so is contention by contention; I'm quite friendly to broader responses as long as they're good responses. I don't mind if you're not too exact on the flow, will assemble clashes myself if I have to, and am happy to cross-apply warrants/weights.
I do not look favourably on most Ks. I will listen to theory but I'll only care if it was relevant to the round itself and the framing/conceptualization of it.
Don't spread but speed is alright.
If you pronounce my full name (Hemanth Bharatha Chakravarthy) right in the first try, I'll bump you up by 1 point. Alternatively, if you cite evidence about something that happened in the Tamil community in India, I'll give you +1.
