The Dunning–Kruger Effect: On Being Ignorant of One’s Own Ignorance

In this chapter, I provide argument and evidence that the scope of people’s ignorance is often invisible to them. This meta-ignorance (or ignorance of ignorance) arises because lack of expertise and knowledge often hides in the realm of the “unknown unknowns” or is disguised by erroneous beliefs and background knowledge that only appear to be sufficient to conclude a right answer. As empirical ...

The "hitchhiking effect" revisited.

The number of selectively neutral polymorphic sites in a random sample of genes can be affected by ancestral selectively favored substitutions at linked loci. The degree to which this happens depends on when in the history of the sample the selected substitutions happen, the strength of selection and the amount of crossing over between the sampled locus and the loci at which the selected substi...

The Zeeman Effect Revisited

The weak field Zeeman effect [1] in simple atoms A = -4(r X B); B = (0,0, B) (2) was one of the earliest problems studied [2] in quantum mechanics. More recently, Ruderman [3] and Theorem 1. Let E~(O)be any negative eigenvalue of then others [4] discussed the analogous problem in the HydrogenHamiltonian H(0). Then there is an eigensuper-strong magnetic fields of the type encountered value [10] ...

The Epps effect revisited

We analyse the dependence of stock return cross-correlations on the sampling frequency of the data known as the Epps effect: For high resolution data the cross-correlations are significantly smaller than their asymptotic value as observed on daily data. The former description implies that changing trading frequency should alter the characteristic time of the phenomenon. This is not true for the...
