3 predictions · 5 assertions · 2 insights · every statement was checked. The predictions and assertions are the 8 claims: statements the public record can support or contradict. 3 are resolved, 1 is not yet assessed, and 4 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.

The record, in short

What the tape says about how Mariana argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.

Their most notable supported claim

Assertion Supported
Wastewater testing can detect influenza, RSV, gonorrhea, and hepatitis C
“It is possible to look at influenza, RSV, other respiratory viruses, to look at gastrointestinal diseases like norovirus, to look at sexually transmitted diseases like gonorrhea or chlamydia, to look at blood-borne pathogens like hepatitis C.”

Expressed certainty vs assessment result

none yet certainty 1
none yet certainty 2
100% certainty 3
100% certainty 4
none yet certainty 5

weighted support: a fully supported claim counts one, a partly supported claim counts half. Each filled bar is clickable and opens exactly those claims; "none yet" means nothing said at that certainty level has resolved yet

How they sound: not measured why? →

We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Mariana Matus on measured tape to publish a rate. This says nothing about how they speak.

Prediction Not checkable as stated
Wastewater platforms will eventually track chronic diseases like cancer and diabetes
“I absolutely see the future where we will have enough data to start to learn kind of predictive components of data To then be able to look at those other more chronic diseases and ultimately, of course, be able to flag a new threat before anybody else knows ab…”

Assertion Supported

Insight
Investors struggle with startups targeting the government as their core early customer
“It's been a challenge for many investors to wrap their heads around this new type of business model and a startup that is proposing to work with government as the target customer, as the core customer from day one.”
Mariana Matus Feb 9, 2023 ▶ 18:17 HIBT Lab! Biobot Analytics: Mariana Matus and Newsha Ghaeli
Assertion Supported
Cary, North Carolina saw a 40% overdose drop using Biobot wastewater data
“The message was embraced by the community, and they saw a 40% decrease in overdoses, which was also the first ever decrease they'd seen in overdoses in their town in almost a decade.”

Prediction Not checkable as stated
Wastewater drug tracking will transform global substance abuse crisis response
“We also absolutely believe that the drug use data that we can collect from wastewater, so use of substances like opioids, meth, cocaine, and other emerging substances, will just transform our ability to understand and to tackle that other crisis that is happen…”
Mariana Matus Feb 9, 2023 ▶ 28:24 HIBT Lab! Biobot Analytics: Mariana Matus and Newsha Ghaeli
Assertion Not publicly verifiable
Less than one percent of genetic data in wastewater originates from humans
“We found that much less than one percent of the genetic data we got back was coming from people.”
Mariana Matus Feb 9, 2023 ▶ 31:59 HIBT Lab! Biobot Analytics: Mariana Matus and Newsha Ghaeli
Prediction Not checkable as stated
Matus: The world will broadly adopt wastewater epidemiology within ten years
“I think that in 10 years, if I look out 10 years, I think that the world will have adopted this type of data collection by large. I think most places will be online, if you will.”
Mariana Matus Feb 9, 2023 ▶ 34:08 HIBT Lab! Biobot Analytics: Mariana Matus and Newsha Ghaeli
Insight
Wastewater is an overlooked, non-invasive source of population health data
“Wastewater had been massively overlooked as a critical source of data to understand population health, and I think that the beauty of tapping into pee, poo, or wastewater as a data source is that we naturally are excreting it out. So rather than needing to be …”
Mariana Matus Feb 9, 2023 ▶ 4:17 HIBT Lab! Biobot Analytics: Mariana Matus and Newsha Ghaeli
Assertion Not checkable as stated
Humans excrete most of their infectious pathogens into the wastewater system
“Based on our research to date and that of other groups we actually end up excreting most of the infectious diseases that infect our bodies.”

Assertion Supported
MIT neighborhood study identified 8:00 a.m. as peak time for bowel movements
“We saw that eight a.m. Seems to be the peak poop time, at least for that neighborhood that we were looking at”
