Money and attention affect how we experience pain and joy. People tend to feel worse when paying with cash compared to using a card. If a restaurant charges you $1 for a spoonful of food, your enjoyment diminishes because you focus more on the cost than the food itself. To reduce spending, you should make spending feel painful. For example, paying with cash rather than a credit card usually leads to less spending. Automatic debit can become a trap. A study shows electricity use increases by 4% when bills are paid via direct debit. Managing spending involves controlling how much importance you give to it. Ultimately, to reduce expenses, we need to change the system and how it’s structured. - Joseph’s “just my thoughts”
Focus on quantity over quality. This will eventually improve quality through quantity. To find the most infected people quickly, you can mix several samples at once and test them many times. What if it mixes? That's okay. You're looking for positives, not negatives, so there will be more negatives in the sample, and if you get positives, you only need to retest the positive group. To increase efficiency, you need to understand the opposite background beyond the target and approach it in terms of quantity rather than quality. This will ultimately improve quality.
