As with virtually anything, I think there are pros and cons. Ultimately, I really don't think it matters much for the overwhelming majority of people. Passively having an account so you can follow some big names, societies, etc. and maybe use it to spot some job ads you'd otherwise miss or follow some interesting conversations is one thing. I actually think the biggest potential advantage - especially as a student - is extracting some useful information from debates that happen. This helps you avoid inadvertently stepping on landmines you didn't know were landmines before some reviewer explodes your torso. Could also help you generate new ideas and build knowledge of what is hotly debated in the field. But it will also suck up time you could spend on things that actually do matter (pubs/grants/etc.).
Spending time "curating" a social media presence is quite another. Nothing wrong with doing that if you want, but I cannot possibly think of a worse reason to have a twitter account than thinking it will help you succeed in academia.
Not all that much different from posting here. Which is something I definitely do for fun and not the professional perks. 15+ years in I think its gotten me 1-2 pubs and one aborted/failed project.
I'd absolutely be more professionally successful if I did NOT read/post on SDN and spent that time writing instead. Yet here I am
Some random notes:
- I actually think it can be more useful for senior folks. When you are an established authority and people will listen to you, it can be helpful for disseminating things. When you are at the stage of publishing your own authoritative textbook then yeah, it may be worth starting to build up an online presence.
- I think linkedin is most valuable for people who don't want academic OR clinical jobs. For academics, linkedin has virtually zero value. With maybe a very tiny asterisk next to that if you do things industry-adjacent enough that consulting gigs might come out of it. Maybe its just me, but I've never been contacted about a remotely viable clinical job on linkedin - this is where they hire contractors to work in prisons for less than my post-docs make. If you want an
industry job than I think a well-designed linkedin profile has some value. It actually IS used in industry.
- I've been on 3 search committees the last two years. Literally no mention of social media was ever made and it was not discussed in a single job application. I recently found out my post-doc does not have facebook. She's worked for me for two years now and I didn't know if she did or didn't.
- Not social media, but the one thing that actually does impress me is when a psychologist has a github. This suggests someone has likely made a useful thing they want to share and is unlikely to be completely technically illiterate. Unless you are in a handful of small subfields though, this is likely irrelevant. I would wager < 20% of my colleagues even know what github is. And to be clear, I do not even have/use github myself.
