Using Validity and Critical Thinking On a Daily Basis

On a daily basis, we hear claims of how this product leads to weight loss, how we should support someone’s awe-inspiring cause, and where we should be spending our time. Invalid arguments are familiar and knowing how to determine whether or not an argument is truthful can help us make choices that lead to better outcomes.

Life is full of people who want you to buy something, sell something, get on a team, and convert to their cause. The list of invalid arguments are nearly endless. Most of us come across inaccurate and invalid arguments that are designed to stir our emotions but have little substance. Knowing valid from invalid arguments helps us see the truth behind the words.

An argument is valid if the premises are true, and the conclusion is not false. Main points should lead to and support the conclusion. In situations where the premises are true but the conclusion is false then the argument is invalid. The premise and the conclusion should hold true.

Even though logic and life may seem different, one leads to the quality of the other. Good choices offer greater outcomes. It is beneficial to try and find your way through arguments by using critical thinking and searching out counter arguments. If you can select counter arguments, the argument becomes open to questioning and more likely invalid.

You can see an example of a statement from a shifty used cars salesman:

“This is a great car because its style is modern. You seem like a guy with great taste, and if you buy this car you are going to be popular as well”.

While it might be true that buying this car is popular and could make you more popular there are many circumstances where this does not hold true. Perhaps you have a great sense of style and decide to buy the car but don’t want your friends to ride in it. If your friends can’t get a ride, they may not like you very much. Maybe the car is in style for people in your grandmother's age group.

The point being that popularity rests only in part on the type of car you drive and more heavily influenced by personality, style, and other issues that make one desirable. The car in and of itself won’t make you the most popular person in town.

It may have been more accurate for the salesperson to say, “This car has sold more models than any other car in the country. You seem to be a guy who cares about his social image. If you buy this car, it will make a statement about who you are.”

This statement is more accurate as the facts about the popularity can be checked with sales numbers. Likewise, research has backed the idea that when we buy a product we are saying a little bit about ourselves. Many of purchase choices are a direct reflection of our personality. The second argument makes it through the "smell" test.

Validity of arguments should maintain a level of internal consistency that helps us know that the premises justify the conclusion. Searching out alternative explanations helps us get a better grasp of what is going on. Flattery with emotionally driven words is not the same as having a logical argument with internal consistency.

Using your logic, reasoning, and fact checking ability, you will be less prone to the false statements that have become part of our lives. Whether it be advertising, a request for a donation, purchasing a car or political support for an idea it is important for you to use your critical thinking skills. It will help you make more accurate conclusions and decisions that lead to advantageous behavior that helps you fulfill your goals.

Drop Out Rates: Should Traditional and Online Schools Have Their Own Rates?




Dropout rates are a primary concern for universities and governments that want to create accountability in higher education. How dropout rates are defined has a large impact on the future success of schools and may influence those that will be around in the future. Some have argued that the timetables and lack of understanding put online schools at a disadvantage under definitions more in tune with the needs of traditional schools.

How Drop Out Rates are Defined

The way in which dropout rates are set can make a large difference in the final rate. For example, if a dropout rate is by course level it will have one value while if it is calculated over a year, or two years, will have another. If calculated over longer periods of times the rates may capture students who bounce in and out of classes but have not given up on their education. When a student drops is confusing.

The government requires the numbers to be calculated each year. These numbers create a rate that is compared with other universities to determine the schools' value. What they don't compare is the background and demographics of the students attending different types of schools and it impacts short-term retention. Some students don't have the full freedom or support to attend college all the way throughout without working.

Different Numbers for Online and Traditional Universities

A study conducted in Spain found that dropout rates would better reflect what is going on if there were a separate definition for online universities (Grau-Valldosera& Minguillon, J. (2014). They believe that the online method of learning is very different from brick-n-mortar institutions and having the same definition doesn’t make a lot of sense.

Students in the online world come from a different background that makes the virtual educational process different than traditional universities. Trying to force online schools into brick-n-mortar models is unfair. As traditional schools move more into online education, they may find similar inaccuracies in reporting.

Online Students are Unique

Students in the online world are more transient and will sometimes attend a few classes and then disappear for a couple of classes before returning. The measurement should be different as those engaged in traditional schooling may never return to an institution once they leave as larger barriers to reentry exist.

There is also another problem related to the preparedness of students. Up to 1/3 of students who enter college are not prepared for higher education through their standard high school education (McMahon, 2015). If online education is serving students with multiple interests and under-served demographics the numbers may be indicative of the challenges in their student populations.

As online schools become more prominent, the very nature and face of education will likely change to incorporate new methods of school evaluation. At present traditional schools are defining the dropout rates leaning heavily in their favor and may not reflect what is occurring in online schools. Coming to a stable definition that reflects both mediums is necessary for an accurate and fair assessment of school quality.

The Sharing Economy Opens a Debate with San Diego Housing Rentals



It isn’t hard to find examples how new technology is disrupting traditional methods of conducting business when these examples are right in your backyard. Homeowners are renting their beach abodes for extra money but putting pressure on local communities that lack parking and resources. Recent meetings with The Smart Growth and Land Use Committee offers opportunities to take public testimony and listen to reports to get a better grasp of how the sharing economy works. 

The problem is not yet a huge one but certainly could get bigger in the future as the sharing economy grows. Getting a handle on it now makes sense. There are around 1,800 registered owners of rental properties but 3,100 properties available for rent (as cited by Fox 5). This means that officials are unaware of how many people are renting homes and whether or not they are complying with regulations.

These rental arrangements are growing in other areas beyond the posh beach communities. Trendy neighborhoods such as East Village, Little Italy and South Park also have their own short-term rental options (as cited by 10 News). It is likely that other communities may have an interest in getting their houses on the market as well.

San Diego is a vacation destination and certainly will have more incentives for homeowners to engage in short-term renting while year round residents feel overwhelmed by the fluctuating traffic. San Diego should not rush to come to grips looming issues in order to set the right tone for other popular resort cities across the country.

As new technology changes the market government must catch up and implement new rules, regulations, and processes to ensure public interest is protected. As government adjusts and changes to meet these new demands government will likely adjust local ordinance, laws, and processes to better manage the situation. The same process will occur throughout the country in other major cities. 

The problems experience in San Diego are not unique as all governments must come to new ways of handling changing trends. There are many legal challenges associated with house renting in the sharing economy and how U.S. policymakers can regulate micro-entreprenuers (Burnette, 2015). These processes will be worked out over time but will come with some turmoil.

At present it is important to hear both sides of the argument and available data to ensure that a solid grasp of the situation is at hand. The changes, legislation and solutions should fit within San Diego’s long-term strategic plan. It is often beneficial to see what other cities and states are doing and adjust those policies to what works best locally. Keeping information available and the public informed of changes is beneficial for community based compliance.
