We have all seen AI-based searches available on the web like Copilot, Perplexity, DuckAssist etc, which scour the web for information, present them in a summarized form, and also cite sources in support of the summary.

But how do they know which sources are legitimate and which are simple BS ? Do they exercise judgement while crawling, or do they have some kind of filter list around the “trustworthyness” of various web sources ?

    I asked if 178bpm was a healthy exercise heart rate, and it told me that 178bpm was a healthy RESTING (meaning not exercising; just sitting or laying down) heart rate. It proceeded to go on about that for two more sentences. This was a few months ago.

      I regularly ask it these questions and have yet to have it too far off of what I’d find from people on any forum.

      Here is me asking it today

      A heart rate of 178 BPM (beats per minute) can be healthy depending on the context:

      ✅ Healthy in Certain Situations:

      If you’re exercising intensely, such as during cardio workouts, running, or high-intensity interval training (HIIT), 178 BPM can be normal and expected, especially if:

      You’re younger (e.g., teens or 20s)

      You’re fit and accustomed to high heart rate workouts

      General formula for max heart rate:

      220 - your age = estimated maximum heart rate So for a 25-year-old: 220 - 25 = 195 BPM max 178 BPM would be about 91% of max, which is high, but acceptable during vigorous effort.

      ⚠️ Not Healthy at Rest:

      If your heart rate is 178 BPM while resting, sitting, or sleeping, that’s too high and could be a sign of:

      Tachycardia (abnormally fast heart rate)

      Anxiety or panic attack

      Dehydration

      Fever

      Heart condition or arrhythmia

      Stimulant or drug effects (e.g., caffeine, medications)

      📌 Summary:

      Situation 178 BPM

      During intense exercise ✅ Normal At rest or light activity ❌ Needs medical attention

      If you’re unsure or it feels abnormal, it’s always safest to consult a doctor.
