Do even papers with the same main author differ in style? What if there are &quot;fraud people&quot; who just write more obscure and their papers are typically frauds?<p>I also wonder how the same approach would apply to politician speeches (does their degree of obfuscation change over time or pre-vs-post election?) or even more directly measurable things such as the FOMC minutes.<p>In the best case we could at least see whether they know they lie (they obfuscate unpleasant truths &#x2F; lies).<p>Then again, it could be difficult to find a dataset with enough positives to train a meaningful categorization algorithm.
