The more I read recommendation letters, the less I want to rely on them.

Many people will disagree with me. But I will still say that:

#AcademicChatter #phdlife #research Image
1. Recommendation letters promote elitism.
“You are not from a famous advisor’s group..? Sorry, you don’t belong here.”

2. When poorly written, a recommendation letter devaluates the candidate.
“This student has such a dull reference… It’s clearly not for us.”
3. Recommendation letters is a way to indirectly control and even intimidate students and postdocs.
“You don’t want to spend 15 hours a day on your research? But then how can I write a good recommendation letter for you?”
4. Recommendation letter can be used to cut opportunities for students (although rarely).
“This student is so good… I don’t want him to go to my competitor’s group and transfer my lab’s expertise there. A dull reference will save me.”
5. Recommendation letter is the reason why students don’t report their advisors’ inappropriate behavior.
“I absolutely need that recommendation letter from my advisor. So I can’t report what he did to me…”
Pros of such letters?
- It saves time during search.
- It helps when the candidate hasn’t published the paper(s) yet.
I was surprised when I found out that a recomm. lett. and advisor’s name ARE what brings many faculty candidates on campus for interview.
I thought it should be the research interests (diversity + depth), prior experience & personal vision. But no, they played a minor role.
Ever since I finished PhD and started looking for faculty positions, I’ve been questioning this approach.

So, is it worth it? Given all the inequity and bias that this approach introduces.

Many people will say: “Yes, it helps us decide on a candidate quickly”.
However, now looking from the PI’s side, I am still inclined to think that no, it’s not worth it.
Recommendation letters can be helpful sometimes.
But there are way too many excellent candidates who were not lucky enough to have “that big name writing a 2-page reference” for them.
Maybe one day we will learn how to assess candidates without references.

But until then, students who want to stay in academia SHOULD be looking for the world-known advisors who (1) know how to and (2) have time to write excellent recommendation letters.

Peer reviewing of manuscripts - is it THAT important as everyone thinks?

I thought of writing this post later, but Nature has catalyzed me to do it now.

Their article mentions the following important points:

#science #research #AcademicTwitter
1. The editor for Frontiers in Health Services sent out 150 (!) invitations to potential reviewers before he could receive 4 reviews. Only 1 was of sufficient quality. That is = 1/150!
2. The pool of reviewers is too small while the number of journals is exploding. This is because the editors often favor well-known scientists from countries with established science infrastructures.

Scientists spend too much time taking “professional selfies”.

A paper from PNAS describes what it takes to be a scientist today. Key points (that I always emphasize myself):

#AcademicTwitter @AcademicChatter #research
1. Scientists have a new mode of activity: “being online”
- Constant distractions and external stimulation inhibit creativity and deep thinking
- “Thinking out of the box” has become rare because the Internet is itself a box.
2. Scientists communicate way too much:
- Easy travel, lots of meetings, tons of emails cause an epidemic of communication. As a result, everyone seems to work in the same direction (within a given field): mass migration to deep learning in AI, to BiFeO3 in ferroelectrics, etc

“Oh, really?” - a typical sarcastic reaction on social media.

However I urge to look at the original study and data more carefully. 👇

#phdchat #AcademicTwitter #research
- A disruptive paper is defined here by the likelihood that this paper (and not the references inside it) will be cited by subsequent studies.

- In contrast, a consolidating paper is the one that is less likely to be cited than its predecessors. It consolidates the discovery.
Importantly, when only articles published in Nature, PNAS and Science or to Nobel-winning discoveries are considered, the downward trend STILL persists.

What explanation do authors suggest for the drop of disruptiveness?

Yes, as a PI, you can publish more papers by pushing your students/postdocs really hard. But NO, those extra papers will not make your life better.

#science #research #AcademicTwitter
They will just make everyone unhappier:
- Your team members will feel burned out and depressed
- Journal editors will feel like there’s another manuscript that no one is willing to review
- The poor reviewers will feel like they have to review a manuscript they don’t care about
- More researchers will feel like they don’t want to get updated about so many papers from your group, especially when their quality gets worse

Advice for #PhD students who want to become postdocs and stay in #academia:
- How to choose a lab for a postdoc
- How to prepare for an interview
- What to be careful about

Thread: 🧵

[I was a happy postdoc at Stanford]

#AcademicTwitter #engineering #science
Initial steps:

1. Decide on how far you want to move away from your PhD topic. Keep in mind:
- If your #postdoc research is distant, you will need more time to gain expertise and do competitive work
- Diverse and strong(!) expertise can make you stand out during faculty interviews and help you establish unique research directions
- BUT: gaining a bit of expertise here and there will hardly give you any advantage in the end

PhD students don’t want to be postdocs. Faculties are leaving academia... Intriguing discussions are published by both Nature and Science.
Key points are:

#science #research #engineering #academia #PhD #AcademicTwitter
1. U.S.-based researchers reported challenges recruiting in all #STEM fields: “This year … we received absolutely zero response from our posting,” one wrote. “The number of applications is 10 times less than 2018-2019,” another wrote.
2. Faculty: “It took 2 months to receive a single application [for a postdoc position]. Money is just sitting there that isn’t being used … and there’s these projects that aren’t moving anywhere as a result”.
