Nudged

You should edit your earlier post to include a link to your correction, too :p

I do not think the apology is justified. All of the publicity surrounding the book uses the examples of 401K defaults and putting nutritious food first in cafeterias. If the authors really wanted to emphasize the libertarianism in their work, they could focus on that.

Sunstein is part of the Obama Administration. Has he proposed any libertarian policies?

What "Nudge" means in the public mind is more paternalism, not less. That is the what the authors want to be known for, as far as I can tell.

The basic problems with nudge remain. All libertarian paternalism usually does is move the onus of federal regulation from voters to employers. It doesn't actually get rid of the coercion, just hides it.
