Hirsch reckons that after 20 years of research, an h-index of 20 is good, 40 is outstanding, and 60 is truly exceptional. In his paper, Hirsch shows that successful scientists do, indeed, have high h-indices: 84% of Nobel Prize winners in physics, for example, had an h-index of at least 30.

Why is my h-index so low?

The number is based on the papers a researcher publishes and the citations those papers get. Publishing a lot of highly cited articles will increase your h-index. On the other hand, getting a lot of citations on only one or two papers will not give you a high h-index.

What is a good h-index by age?

It is simple to calculate. But what should be a good h-index? Hirsch2 was of the opinion that 20 h-index is Good,40 is Outstanding and 60 is Exceptional but after 20 years of research life.

What is the h-index for Nobel Prize?

Hirsch has demonstrated that h has high predictive value for whether a scientist has won honors like National Academy membership or the Nobel Prize. The h-index grows as citations accumulate and thus it depends on the "academic age" of a researcher.

Is 1,000 citations a lot?

Most authors of highly cited papers have fewer than 1000 citations, which is very little in comparison with the highest numbers indicated in the top part of Table S1. Table S1 shows a high degree of rank–rank correlation between the number of citations, h-index, and scientific degree, which are over 0.9 (citations vs.

What is the highest h-index ever recorded?

Who won the Nobel Prize with a low h-index?

Clauser is not the only one. Harry Kroto, the 1996 winner of the Nobel Prize in Chemistry, did not have a high h-index; in fact, a single publication earned him the prestigious award. John F.

What are the disadvantages of the h-index?

The limitations of the h-index include: 1. It does not take into account the total number of citations. For example, imagine that another scholar also has 15 publications, and also 8 of them have more than 8 citations, but each of the first five were cited more than a thousand times.
