What is availability bias?
Data Literacy Uncertainty and Misinformation
Sarah Whitley Coles, MD
Tl;dr: Availability bias, also called availability heuristic, is a type of cognitive bias that occurs when we rely disproportionately on the most readily available information to make decisions or judgments rather than the most representative or accurate data. Reflection and review of all available data can help us mitigate this particular bias. Sometimes do you Read more…
How can I boost my child’s immunity to misinformation?
Data Literacy Uncertainty and Misinformation
To help your child separate fact from fiction, teach them to: be skeptical, use credible sources, think critically, and embrace learning through science. Start early, and weave these lessons into everyday life. Back when we were young, we Nerdy Girls used encyclopedias, reference books, and textbooks to learn. These days, we are surrounded by a Read more…
Are we over-counting Covid deaths?
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
No. Sadly, we are most likely still UNDER-counting Covid-19 deaths. Among the most persistent COVID-19 myths is the idea that COVID-19 deaths are being over-counted, which recently resurfaced in a Washington Post editorial. We’ve all heard stories of COVID positive motorcycle accident victims being counted or the saying that people are dying *with* COVID-19 rather Read more…

Life Expectancy Update 2021
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
In many countries, life expectancy dropped substantially in 2020 due to COVID. Did life expectancy bounce back in 2021, or did things get even worse? TL;DR: A mixed bag, w/ greater divergence of experiences as the pandemic wore on. While Western Europe saw improvements from 2020, the US and Eastern Europe saw continued losses. Read Read more…
I heard that US life expectancy fell again. Does this mean *my* lifespan will be shorter?
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
A: Not necessarily. Despite the name, life expectancy doesn’t predict the lifespan of individuals. But as a “snapshot” of mortality in the US, the news is not good. Recent U.S. CDC estimates show a loss of a 2.7 years of life expectancy in 2021 compared to 2019. Surprisingly, despite the vaccine roll-out, U.S. life expectancy Read more…
What is confirmation bias? What is motivated reasoning? How do they impact the spread of misinformation?
Data Literacy Uncertainty and Misinformation
Amanda Simanek, PhD MPH
A: Confirmation bias happens when we accept information that confirms our pre-existing ideas or beliefs, but ignore or question information that does not. Motivated reasoning happens when we only seek out information that confirms what we already think is true. Both ways of distorted thinking can lead us to share information without critically assessing it Read more…
Why do long COVID estimates seem to vary so much from study to study?
Data and Metrics Data Literacy Long COVID
Amanda Simanek, PhD MPH
A: Different case definitions, study participants, data collection methods, and study timing across studies. TL:DR: Current estimates of the proportion of COVID-19 cases that develop long COVID range from 3-20% and have been as high as 50%! Considering how studies differ can help us understand why estimates vary so much across studies. Things to keep Read more…

What is sensitivity and specificity, and why should I care?
Data and Metrics Data Literacy
Sarah Whitley Coles, MD
A: Good question! Sensitivity and specificity are characteristics of a medical test that help us determine how useful that test is and how to interpret the result. BUT, they aren’t the be all and end all. We also want to know the positive and negative predictive value. Strap in for the ride and let’s talk Read more…
With so many people using home tests (which mostly go unreported), how can we rely on COVID-19 data to understand community levels of transmission?
Data and Metrics Data Literacy Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: With more people using home rapid tests interpreting local COVID-19 data does become murkier, but a useful addition is wastewater surveillance! TL; DR Keeping an eye on local wastewater surveillance can help round out understanding of community transmission as it doesn’t rely on testing or reporting of test results. ✳️Home testing is great because Read more…
Q: If 50% of COVID hospitalizations are among the vaccinated, does that mean the vaccines aren’t working?
Data and Metrics Data Literacy Vaccines
Kristen Panthagani, MD, PhD
A: No. This metric sounds useful, but it can’t tell us anything about vaccine effectiveness. Since the roll-out of COVID vaccinations, many headlines have reported the percent of COVID hospitalizations and deaths who were vaccinated, trying to convey how well the vaccines are working. ‘Only 1% of COVID hospitalizations are vaccinated people’ sounds encouraging, doesn’t Read more…
Is COVID-19 99% survivable?
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
A: Yes- BUT those odds are not as good as they sound. Ask yourself- would you let your family board a plane if 1 out of 100 passengers were going to be thrown out of the plane mid-flight? We continue to hear the “99% survivable” argument as a reason not to get the COVID-19 vaccine. Read more…
Are we over-stating COVID-19 mortality?
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
A: No. It’s bad. ➡️ The Covid-19 pandemic has resulted in the largest loss of life expectancy seen in many countries since World War II. ⬇️ U.S. males saw some of the worst losses—2.2 years of lost life expectancy in 2020. The drop was 1.65 years for U.S. females. We’ve talked about “excess mortality” in Read more…
What is the real COVID-19 death toll? Are we over-counting deaths?

Q: I heard 40% of COVID hospitalizations in the UK are among the vaccinated. What’s going on, this sounds bad? A: This is a confusing statistic, for sure. This number is actually good news and reflects the really high vaccine coverage of the older population in the UK. 🙋♀ Wait, what now? Let me explain! Read more…
Are over-the-counter COVID-19 tests reliable?
Data and Metrics Data Literacy Testing and Contact Tracing
Chana Davis, PhD
Over-the-counter COVID-19 tests are now available in the United States. For 30 to 50 bucks, you get an answer in 25-45 minutes in the comfort of your home, much like the free rapid antigen tests used in the UK. Can you trust the results? It depends. Dr. Chana Davis from Fueled by Science gives us Read more…
What is the real COVID-19 death toll? Are we over-counting deaths?
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
A: Sadly, we are most likely UNDER-COUNTING Covid-19 deaths. Among the most persistent COVID-19 myths is the idea that COVID-19 deaths are being over-counted, including stories of victims of motorcycle accidents getting tested in the hospital so they can be counted as COVID-19 deaths, or the infamous line that people are dying *with* COVID-19 rather Read more…
In many countries, life expectancy dropped substantially in 2020 due to COVID. Did life expectancy bounce back in 2021, or did things get even worse? TL;DR: A mixed bag, w/ greater divergence of experiences as the pandemic wore on. While Western Europe saw improvements from 2020, the US and Eastern Europe saw continued losses. Read Read more…
I heard that US life expectancy fell again. Does this mean *my* lifespan will be shorter?
Data and Metrics Data LiteracyJennifer Beam Dowd, PhD
A: Not necessarily. Despite the name, life expectancy doesn’t predict the lifespan of individuals. But as a “snapshot” of mortality in the US, the news is not good. Recent U.S. CDC estimates show a loss of a 2.7 years of life expectancy in 2021 compared to 2019. Surprisingly, despite the vaccine roll-out, U.S. life expectancy Read more…
What is confirmation bias? What is motivated reasoning? How do they impact the spread of misinformation?
Data Literacy Uncertainty and Misinformation
Amanda Simanek, PhD MPH
A: Confirmation bias happens when we accept information that confirms our pre-existing ideas or beliefs, but ignore or question information that does not. Motivated reasoning happens when we only seek out information that confirms what we already think is true. Both ways of distorted thinking can lead us to share information without critically assessing it Read more…
Why do long COVID estimates seem to vary so much from study to study?
Data and Metrics Data Literacy Long COVID
Amanda Simanek, PhD MPH
A: Different case definitions, study participants, data collection methods, and study timing across studies. TL:DR: Current estimates of the proportion of COVID-19 cases that develop long COVID range from 3-20% and have been as high as 50%! Considering how studies differ can help us understand why estimates vary so much across studies. Things to keep Read more…
Evaluating Medical Literature: Patient Oriented Evidence vs. Disease Oriented Evidence
Data and Metrics Data Literacy
Sarah Whitley Coles, MD
Results of medical studies are often reported in the news. You may have seen headlines like “What vegetable on your dinner plate is killing you?” or “New study shows Medicine X causes memory loss!” You are, very likely and very appropriately, highly skeptical of these headlines but it can be really tricky to sort out Read more…
Series on Logical Fallacies – “Who funds you?”
Data Literacy Uncertainty and Misinformation
Kristen Panthagani, MD, PhD
At Dear Pandemic, we want to dish out science facts AND equip our readers with tools to make sense of data and science themselves. This is post is part of an ongoing series by Dr. Kristen Panthagani of You Can Know Things, in which she dissects common logical fallacies that have led people astray during Read more…
What is sensitivity and specificity, and why should I care?
Data and Metrics Data Literacy
Sarah Whitley Coles, MD
A: Good question! Sensitivity and specificity are characteristics of a medical test that help us determine how useful that test is and how to interpret the result. BUT, they aren’t the be all and end all. We also want to know the positive and negative predictive value. Strap in for the ride and let’s talk Read more…
With so many people using home tests (which mostly go unreported), how can we rely on COVID-19 data to understand community levels of transmission?
Data and Metrics Data Literacy Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: With more people using home rapid tests interpreting local COVID-19 data does become murkier, but a useful addition is wastewater surveillance! TL; DR Keeping an eye on local wastewater surveillance can help round out understanding of community transmission as it doesn’t rely on testing or reporting of test results. ✳️Home testing is great because Read more…
Q: If 50% of COVID hospitalizations are among the vaccinated, does that mean the vaccines aren’t working?
Data and Metrics Data Literacy Vaccines
Kristen Panthagani, MD, PhD
A: No. This metric sounds useful, but it can’t tell us anything about vaccine effectiveness. Since the roll-out of COVID vaccinations, many headlines have reported the percent of COVID hospitalizations and deaths who were vaccinated, trying to convey how well the vaccines are working. ‘Only 1% of COVID hospitalizations are vaccinated people’ sounds encouraging, doesn’t Read more…
Is COVID-19 99% survivable?
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
A: Yes- BUT those odds are not as good as they sound. Ask yourself- would you let your family board a plane if 1 out of 100 passengers were going to be thrown out of the plane mid-flight? We continue to hear the “99% survivable” argument as a reason not to get the COVID-19 vaccine. Read more…
Are we over-stating COVID-19 mortality?
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
A: No. It’s bad. ➡️ The Covid-19 pandemic has resulted in the largest loss of life expectancy seen in many countries since World War II. ⬇️ U.S. males saw some of the worst losses—2.2 years of lost life expectancy in 2020. The drop was 1.65 years for U.S. females. We’ve talked about “excess mortality” in Read more…

A: Sadly, we are most likely UNDER-COUNTING Covid-19 deaths. Among the most persistent COVID-19 myths is the idea that COVID-19 deaths are being over-counted, including stories of victims of motorcycle accidents getting tested in the hospital so they can be counted as COVID-19 deaths, or the infamous line that people are dying *with* COVID-19 rather Read more…
At Dear Pandemic, we want to dish out science facts AND equip our readers with tools to make sense of data and science themselves. This is post is part of an ongoing series by Dr. Kristen Panthagani of You Can Know Things, in which she dissects common logical fallacies that have led people astray during Read more…
What is sensitivity and specificity, and why should I care?
Data and Metrics Data LiteracySarah Whitley Coles, MD
A: Good question! Sensitivity and specificity are characteristics of a medical test that help us determine how useful that test is and how to interpret the result. BUT, they aren’t the be all and end all. We also want to know the positive and negative predictive value. Strap in for the ride and let’s talk Read more…
With so many people using home tests (which mostly go unreported), how can we rely on COVID-19 data to understand community levels of transmission?
Data and Metrics Data Literacy Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: With more people using home rapid tests interpreting local COVID-19 data does become murkier, but a useful addition is wastewater surveillance! TL; DR Keeping an eye on local wastewater surveillance can help round out understanding of community transmission as it doesn’t rely on testing or reporting of test results. ✳️Home testing is great because Read more…
Q: If 50% of COVID hospitalizations are among the vaccinated, does that mean the vaccines aren’t working?
Data and Metrics Data Literacy Vaccines
Kristen Panthagani, MD, PhD
A: No. This metric sounds useful, but it can’t tell us anything about vaccine effectiveness. Since the roll-out of COVID vaccinations, many headlines have reported the percent of COVID hospitalizations and deaths who were vaccinated, trying to convey how well the vaccines are working. ‘Only 1% of COVID hospitalizations are vaccinated people’ sounds encouraging, doesn’t Read more…
Is COVID-19 99% survivable?
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
A: Yes- BUT those odds are not as good as they sound. Ask yourself- would you let your family board a plane if 1 out of 100 passengers were going to be thrown out of the plane mid-flight? We continue to hear the “99% survivable” argument as a reason not to get the COVID-19 vaccine. Read more…
Are we over-stating COVID-19 mortality?
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
A: No. It’s bad. ➡️ The Covid-19 pandemic has resulted in the largest loss of life expectancy seen in many countries since World War II. ⬇️ U.S. males saw some of the worst losses—2.2 years of lost life expectancy in 2020. The drop was 1.65 years for U.S. females. We’ve talked about “excess mortality” in Read more…
What is the real COVID-19 death toll? Are we over-counting deaths?
Data and Metrics Data Literacy
Jennifer Beam Dowd, PhD
A: Sadly, we are most likely UNDER-COUNTING Covid-19 deaths. While the official global death toll from Covid-19 is now 4.6 million, the actual toll is estimated to be close to 15.4 MILLION people. Among the most persistent COVID-19 myths is the idea that COVID-19 deaths are being over-counted, including stories of victims of motorcycle accidents Read more…
What is the difference between absolute risk and relative risk and why on Earth should I care?
Data and Metrics Data Literacy
Sarah Whitley Coles, MD
A: It turns out, how we describe risks REALLY matters and helps us better understand our healthcare choices. Read below for a review of how risk is calculated and communicated (and can be used for trickery!). The TLDR version: Absolute risk reduction is the number you actually want to know most of the time. Buckle Read more…
Why are 40% of COVID hospitalizations in the UK among the vaccinated?
Data and Metrics Data Literacy Vaccines
Jennifer Beam Dowd, PhD
Q: I heard 40% of COVID hospitalizations in the UK are among the vaccinated. What’s going on, this sounds bad? A: This is a confusing statistic, for sure. This number is actually good news and reflects the really high vaccine coverage of the older population in the UK. 🙋♀ Wait, what now? Let me explain! Read more…
Are over-the-counter COVID-19 tests reliable?
Data and Metrics Data Literacy Testing and Contact Tracing
Chana Davis, PhD
Over-the-counter COVID-19 tests are now available in the United States. For 30 to 50 bucks, you get an answer in 25-45 minutes in the comfort of your home, much like the free rapid antigen tests used in the UK. Can you trust the results? It depends. Dr. Chana Davis from Fueled by Science gives us Read more…
