Does H-index reflect the quality of researchers?

Do you think h index is an appropriate index to evaluate a researcher? What alternative do you suggest?

I think, h index is not an appropriate index to assess a researcher. For instance, a paper could be regularly cited because other researchers are refuting its results. Generally, big research groups in some fields can generate many original research articles, each article with dozens or hundreds of authors. People of these research groups would often display extremely high impact metrics that could not truthfully reveal their individual prominence within the area.

The H Index is the best way of assessing the researcher as in cases where the researcher is just described orally or by paper without seing exactly what was done it becomes bias.

The h index is important, but not enough to fully assess the researcher. In addition, the indicators that indicate the academic rank and the duration of the research activity should be considered in the researcher's assessment.

I think it does as the evidence in different fields is showing that, The following articles are some examples:

YES, you're right, this point is important for many researchers particularly who are at the beginning of their research career. I think a researcher who has high a H index we can consider their works and we can count on his school
but not all H indexes are real because some companies count H index through many fake journals so we must be ensure the source of H index before considering it

In my opinion, h-index is the main parameter that could evaluate the quality of a researcher. Because it is directly related to the research publications and some other outcomes of a researcher.

I do not know how exactly the h-index is calculated. If all authors in the paper are awarded equally, the h-index might not represent the quality of researchers.

I agree .There could be another index reflecting only citiation for corresponding author. ?f you are not corresponding author or first name in the publication or senior (last name in the pub) it should be eliminated from the list.

Personally, I would prefer an index in which papers are weighted to account for the impact factor of the journal, number of co-authors and position in the authors' list. For instance, a 2017 paper in a journal with the impact factor "IF", and "n" authors should count as "IF/n" multiplied by 3 for the first author, by 2 for the last author and by 1 for each other author. If the first or last position is shared by two or more authors, than the 3 or 2 points should be divided accordingly. For journals with no impact factor, one can consider a flat IF = 0.1. Thus, all your papers will be included, the audience of the journal considered and your direct contribution to that paper acknowledged. It will limit the courtesy authorship offered to "important" people or addition of lab students and other members with no contribution just because the PI needs to show what a good supervisor s/he is.

I don't think its a good measure of a researcher. There's a bias toward big studies that get cited numerous times..for example if you are a scientist working in an institute that is a contributor to large scale sequencing projects, you will be one of the usually dozens of authors on the paper, and you will likely get cited thousands of times. But your contirbution to the overall project may be less than another researcher who is one of a small team that did a much bigger segment of work on a smaller project, albeit published in a lower impact factor journal and not cited as much.
But it's better than just looking at impact factor of the journals so there is some benefit to it. I think the above problem should be sorted out though.

The h-index is important as it demonstrates the quality and not quantity of the researcher (3 big studies in nature or science or NEJM would likely yield a higher h index rather than 25 studies in lower impact journals) however h index increases with more time if continued research is done (i.e. a professor should have a higher score vs an assistant professor)

Not entirely, reflective of the quality of researchers or appropriate index for evaluating a researcher. Rate of citation is not quality indicator. Besides, h-index could be influenced by self-citation.

Normalement, oui. cependant, la vrai valeur d'un charcheur est la qualité de ses recherches et son niveau intellectuelle; il se peut que quelqu'un est un très bon chercheur néanmoins, le manque de moyens le déclasse.

H index is a good parameter to evaluate the quality of a researcher. However, the index also depends upon the citation for each paper. There are many excellent papers with no citation. Hence, it cannon be the only criteria to evaluate the quality of researcher.

I think H index, reflecting the academic and scientific quality of the researcher and his production capacity. H index is the result of the balance between the number of publications and the number of citations.

Before we discuss the appropriate index to evaluate a researcher, we need make a conclusion what kinds of researcher is good ones. Good publications? good application of their research? or a lots honors from them? Actually, all information are used to evaluate a research.

Unfortunately it is not accurate especially for researchers publishing plenty of papers. I think that a special score should be done taking into account both the quality of work and the reputation (including impact factor) of the journal.

H- index is a good measurment of research performance, but it is not the only measurement because the application part of the research works may not be evaluated by H-index only.

In my opinion, H- index can be one of the tools for measuring the quality of researchers, but it's not enough alone. It is also important whether researches that have been done by a researcher are on a continuum or not.
