Hear, hear‼️ Health misinformation erodes autonomy‼️ Vaccine mis- and disinformation isn’t just a threat to public health, but also to our autonomy theconversation.com/vaccine-mis-... "If we value autonomy for what it really means ... we must take action to address mis- and disinformation."

Vaccine mis- and disinformation isn’t just a threat to public health, but also to our autonomy

When we are mis- or disinformed, it is difficult to act with autonomy. We may make decisions that do not align with our beliefs, even when we seem to be acting voluntarily.

Is the Extra Protein RFK Jr. Recommends Really Good for Us? conscienhealth.org/2026/08/04/i... @conscienhealth.bsky.social "The evidence does not support protein evangelism any more than it supported fat phobia or carb panic. Yet our public conversation has once again raced ahead of the evidence."

Is the Extra Protein RFK Jr. Recommends Really Good for Us? - ConscienHealth

A new scientific review suggests the advice from RFK Jr. to consume extra protein may not be optimal for healthy aging across the board.

Testosterone & military: www.nytimes.com/2026/07/30/s... "...no medical groups recommend universal screening ...could lead to overtreatment..." "...makes aggression more rewarding" "...can cause a dangerous thickening of the blood" "...shuts down sperm production, which could harm fertility"

I hate the hindsight bias & revisionist history fuelled "middle ground fallacy" emerging (in media, politically, etc) around the attack on Fauci. We all (read: those who support science, justice, rationality, decency, reality...) need to stand against the lies, spin, and corruption.

In RFK Jr's attack on #Fauci, he lied about COVID deaths, he lied about vaccines, he lied about ICUs, he lied about "censoring", etc Reality: 👉 MAGA #misinformation – especially about vaccines – killed people 👉 It is MAGA dismantling "our constitutional rights" www.poynter.org/commentary/2...

Dana Bash did her job — and RFK Jr. didn’t handle it well - Poynter

The health secretary turned a discussion about COVID and vaccines into a combative back-and-forth while Bash kept asking the questions that mattered

Hey anonymous internet people, I'd like to start taking an experimental hormone with vaguely defined benefits. I know I could self-experiment by ordering from a random website, but I'd rather pay an unethical grifter to spin lies to me first before I inject myself with a mystery substance. Any tips?

Post in FB group Crunchy Moms Canada:

Does anyone know of any Naturopaths or Drs in southern Alberta that help you get started on Peptides? Not just for weight loss but for healing injuries and inflammation. I know you can order online but I would like some guidance and information.

So infuriating to watch the continued use of misinformation, spin, and revisionist history to attack a person who has spent his life dedicated to science & public health. My experience: #Fauci thoughtful, kind, and committed to making the world better. MAGA fuelled by lies, hate, and rage.

Business of FEAR 👇 Gun Ownership Among US Women jamanetwork.com/journals/jam... "...perceptions of risk and safety are driving firearm sales..." "69.7% of women who personally own firearms believe doing so makes them safer," despite a HUGE amount of evidence to the contrary. Guns ≠ safer.

Gun Ownership Among US Women

⚠️ Sum: Put down the phone! It is pulling you into a cycle of stress! Scrolling endlessly to unwind? It could be making you feel worse. www.washingtonpost.com/lifestyle/20... From study: "greater neglect of other areas of life, longer use times, & more stress as well as worse mood in daily life."

Scrolling endlessly to unwind? It could be making you feel worse.

A new study finds that spending more time on the internet can make you feel grumpier and more stressed. But there are ways you can cut back.

How badly has #misinformation been normalized? An increasing % of people believe the unhinged idea that the COVID vaccine killed more than COVID. 27% think true‼️ ONLY 39% know definitely false‼️ Reality: COVID killed > 7 million. Vaccine saved millions & severe adverse reaction extremely rare.

Influencers – often the same MAHA grifters worried about food dye & seed oil (sigh) – pushing tanning wapo.st/4hH2WQz cc @cancersociety.bsky.social 52% of youth say "tan on purpose" ‼️ "...skin #cancer is the most common type of cancer..." #Misinformation ➕ "tanfluencers" 🟰 deadly trend.

Tanning is trending, but is it ever safe? Here’s what dermatologists say.

Influencers are glamorizing tanning. But experts want you to think twice before heading outside to intentionally bronze your skin.

So much upsetting about the Fauci attacks. But it also demonstrates the COMPLETE absorption & normalization of hardcore lies and conspiracy theories by the political right (alas, same here in Alberta). Reality irrelevant. Rage & grievance dominate.
